I have one of these and the BT board is worth mentioning.
My unit is a 10 inch KLYDE MTCC unit for Suzuki Vitara but I saw several models including this board.
These units have a Parrot FC6000TN daughterboard that has two MAJOR improvements over generic boards.
1. Call quality is very good, even with the unit's mocrophone. No longer hisses and voice breaking.
2. Voice command. I have no idea how it is implemented but if you have one of these boards you will have an extra microphone icon on your home screen. The current implementation only accepts 2 commands, CALL and DIAL but it works amazing. As good as OK Google only ten times faster You can see a demo in this video
It's definitely worth a look since this board can do so much more. I found a specs file that says:
The FC6000T is a feature-rich Bluetooth platform dedicated for the integration of Bluetooth in car audios, car telematics systems or any systems requiring a complete embedded multimedia solution.
FC6000T features are:
• Bluetooth connectivity
Bluetooth Power Class 2 Radio
Embedded Bluetooth .1, v1.2, v2.0+EDR, v2.1+EDR & v3.0 compliant
Bluetooth v4.0 : future implementation
Embedded profiles
Compatible with most of Bluetooth phones
Pairing and connection with all Bluetooth Devices: Phones, Smartphones, PDA …
Multiple users support: Up to 10 paired phones depending on Flash memory size.
Multiple connections (up to 3 device connected at the same time)
Multiple profiles
• Phone
Pick-up, Hang-up, Redial
Automatic answer (from host via pickup command)
Send DTMF during calls
Private Mode
3-way calling
Double HFP
Phone Book
Automatic Phone book synchronization over Bluetooth (up to 5000 contacts; depending on the Flash memory size)
Call history (dialed number, received calls, missed calls)
All Synchronization Methods
Full Unicode for compatibility with numerous characters sets (European, Russian, Chinese, Japanese…)
• Digital Signal Processing
Microphone(s): the module can manage two configurations:
Single microphone
Two microphones with AMS (Automatic Microphone Selection): 1 for the driver and 1 for the front seat passenger. The best microphone is automatically selected during the call.
Noise Reduction (NR)
Maximal NR is 25dB.
Typical NR is 15dB.
No musical noise
No fluctuation of the residual noise level
Automatic adaptation of the Noise Reduction to the Signal-to-noise ratio (SNR) to keep the best voice quality in idle and remove more noise in noisy conditions.
Acoustic Echo Cancellation (AEC)
The level of echo attenuation, called ERLE is 45dB (measured according to the VDA process).
Comfort Noise feature so that the background noise is adjusted after AEC algorithm, in order to keep it constant for enhanced communication experience.
Possibility to accept up to 100ms of delay in the speaker path for digital amplifiers.
Full duplex
Automatic Level Control (ALC)
Different phones can have different Speaker volumes (up to 20dB of difference). It adapts the signal level received from the phone to the target level, quickly and precisely.
Equalizer
9 bands equalizer for microphones and speaker paths.
Tuning
Car independent tuning if the microphone position and specifications are the same.
Possibility to tune all parameters of the audio algorithms according to Customer preferences.
Wideband
All algorithms work @ 16 kHz.
Audio Streaming
Embedded SBC decoder
Embedded MP3 decoder from Thomson Licensing (optional)
Stereo audio output
• Speaker Independent Voice Recognition (Optional)
Klyde have mentioned this several times, but you are the first person on here to have one.
Hmmm it'd be interesting to see if this could be installed on boards without parrot installed. My units Bluetooth is horrible =/

It definitely can be installed. My unit had standard BT and the Parrot board was optional. Before ordering I made sure the Parrot BT option actually means the replacement of the internal BT board with a Parrot one. Before buying it I talked to several vendors that were offering this Parrot BT option and found out that some will actually send you an external Parrot BT module :laugh:

If you knew the name of the Parrot module you could source it from somewhere else, not necessarily a headunit vendor.

Most certainly. It shows in Factory Settings as FC6000TN and it's the one advertised by most vendors for new units - see Pumpkin. It comes with MTCC units.
I wish I had taken some pictures before setting it in the car. Maybe there will be new users with this kind of setup. If that doesn't happen soon, I'll take mine out and take a few pictures.

Right, the point is you could potentially source it from anywhere.
By upgrading the Bluetooth, isn't the parrot just as handicapped as the other BT modules anyway?
From my understanding it routes all communication through the MCU via serial and the kernel is non standard Bluetooth.
So 90% of the features listed in post 1 probably don't work????

You're probably right, since I've a Parrot BT in my Pumpkin and it's only a minor improvement. Taking away
the internal, making it external, improved a lot as on regular units.

I have been in constant communication with Eonon for about 4 months about adding external USB support, as the internal one is not very good and they would need to reconfiguring the kernel to support such feature.
As long as it supports a common generic BT adapter with BT 4.0 I would be happy.
Eonon ensure me that they do have inhouse developers working on the unit, but it must be in collaboration with klyde as they are all connected.
Funny enough the Klyde units do support external Wifi RTL8192CU dongles, works heaps better than the internal one, so adding external BT can't be much of a stretch.
Be nice if someone found a way to bypass the MCU and directly connect the BT to the SOM (soldering required), kind of like what 7floor does with sound.

Yep fully aware of the situation as you have mentioned many times before.
And yes I have tried a Bluetooth dongle on the new October firmware with 2.98MCU
Even turned bluetooth off in the MCU and no change, it will not recognise USB BT.
Drivers must have been removed by KLYDE or never added to the kernel at all.

I have asked DSA8310 before he said no
Agentdr8 sums it up quite nicely as well, this is something the factory needs to add
agentdr8 said:
Since the kernel is not open source, there's very little hope of adding the necessary drivers to support external BT adapters. Aside from that, I don't believe the BT stack that is included in these roms is standard.
I won't say it's impossible, as given enough time and money, anything is possible. But I doubt it's something anyone here can address without the sources.

Right, well maybe the octacore versions will have a different solution.
There are currently some MTCD versions with Rockchip/Intel (1.2 Ghz, 2GB RAM) quadcore boards that have the wifi and BT on the SoM and not controlled by the MCU :
http://forum.xda-developers.com/and...opment/2gb-ram-intel-cpu-heres-specs-t3468322

There are several DAB options for MTCB head units :
1)The RTL type DVB-T/FM dongle and the Wavesink app, see this thread in the hardware mod section: http://forum.xda-developers.com/and...development/adding-dab-functionality-t3208344
2) Use DVB-T card or module specifically for MTCB head units and use the "radio" function. These can be bought with the head unit or purchased separately. Some manufacturers like KGL/HuiFei use and add on box, others like Klyde, use cards mounted inside the unit. In factory settings, at the last count, there were about 12 different types of TV tuner that can be selected.
3) Or use general Android USB DVB-T dongle and use the "radio" setting on its accompanying app. If this method is chosen, obviously you dont need to go into factory settings and pick a tuner, as these settings are only for DVB-T tuners bought with/for MTCB head units.
(Radio through a DVB-T card IS digital (using either MPG2 or MPG4 depending on the type of DVB-T tuner you have) but it is not DAB. Its also dependant on what radio channels your country chooses to transmit over DVB-T, for instance in the UK in my local area, none of the local stations are transmitted and not all of the national ones are either.)
4), 5) & 6) Dension sell 3 Android DAB products, one that uses BT to connect (which may prove a problem with the BT implementation on MTCB head units, edit: May 2016, the BT type seems to no longer be available), one that connects via USB and 1 that uses FM modulation (which means station names/info displayed via RDS in the FM/AM radio app, but a separate controller for the DAB for changing channels is needed) see here : http://www.dension.com/products#dab-radio-solutions
7) Navall sell a DAB module for their units, they sell both KGL (Hui Fei) units and also the Ownice head unit (the Ownice is NOT an MTCB type unit) see here : http://navallstore.com/Options/DAB -DAB-plus(Digital-Audio-Broadcasting)
8) Joying sell an add on DAB box (its not L band compatible though) : https://www.carjoying.com/joying-di...iversal-android-car-auto-radio-head-unit.html
9) FIAMM make a DAB antenna with built in tuner and BT, so youd simply install the antenna and use BT on your head unit to connect to BT (there is an app available), how it would work with the BT on MTCB head units, however, is unknown :
http://www.smartantenna.it/en/page-product.php
https://play.google.com/store/apps/details?id=com.fiamm.sm2&hl=en
10) And finally Klyde sell a DAB module specifically for their units (I ve just bought a new Klyde head unit with it). They use a DAB module made by Shinwa who also supply DAB modules to Blaupunkt, Pure and Philips. I m told it is not retro fittable as modifications are needed to the board, I ve tried to make it work on my non DAB Klyde unit. but I ve had no luck, so far at least. Its a separate module, but its quite small (approx 10cmx4cmx5cm). Its small enough to be mounted inside the unit, something I intend to do with mine. It uses the DAB app that started appearing in ROMs from June (2015), although they have recently updated it. I ve added pictures of the module and the new app. It works quite well, although I m not over keen on the interface of the app personally, but it can be modded like any other MTC app. As the DAB app appears in ROMs since June, its been developed by MTCB (who develop ALL the software for ALL the MTCB type headunit, which is why they are so similar and have interchangeable software, WHICHEVER manufacturer version you have) this may mean that the other manufacturers will have OEM DAB options soon - I m sure MTCB have not developed the DAB app just for Klyde. So far at least, Klyde is the only company selling DAB units that use this app, AFAIK Navall use a different app and set up.
Sweet! I may replace my current hu in the near future then; quad core and dab+ would be worth it
Does the app not give you channel list? Only next/prev?

Soz for delay, I m not getting emails when my posts get replies, for some reason.
Yeah, there is a channel list, you press the menu button on the top left I think, its hard to tell cos I using it with horizontally mounted DVB-T antennas so I only get that channel currently, I need to get a proper DAB antenna !
I ll change this thread to a general "DAB for MTCB Headunits" thread soon and list all the DAB/digital radio options - basically the Navall DAB module, RTL DVB-T tuners with Wavesink, this DAB module from Klyde and using a DVB-T card/module/usb TV dongle to receive digital radio through digital tv).

I saw the other thread, but that was specifically for using the Wavesink app with RTL dongles, which is technically a hardware "mod" as you are adding hardware, whereas this was meant to be a general DAB/digital radio guide, hence putting it in the "general" section, also, if you buy a unit with DAB already, its not a "mod". I ve added a link to the Wavesink DAB thread. Maybe you could re-name that thread "Using Wavesink for DAB" or something ? I think you d have to re-name this one as well, as I dont think threads can be re-named by non mods (take it youre a mod now Alex ?!), can you re-name it "Guide to DAB on MTCB headunits" ? And if there are threads about DVB-T dongles, the Dension DAB options and DVB-T tuner supplied with MTCB head units (I know all have been discussed in the original thread) I can add links to them in this thread also.
(Need to reply to your pms BTW Alex, I will do soon)
@dark alex - I found out how to edit the thread title - double click to the right of it before you go into the thread, changed title !
is there somewhere to get an updated apk for the DAB app for the pumpkin headunit, the one on it at the minute is dross....it wont store stations and if you switch screen views it dumps all it had 2 seconds before
Hi sorry for my english.
I'm italian. Dab is not diffuse.
My problem is mct radio because the AF not work. So i think to buy an external FM USB receiver.
Aswers:
1 Which i must buy?
2 can i connect car antenna directly to usb receiver?

@typos1 - would you please share your Klyde DAB apk ? From the picture it seems you have some newer version than I do. Thanks.
Sure its on the fileserver in the "apps" section.
Volume
has anyone using the new DAB app found out how to lower the volume so you can hear the navigation voices? the volume seems too loud and all other sounds are quiet?
This Klyde DAB+ unit sounds through Android or just you can control over Android and sounds trough MCU like the FM radio?

@typos1 , have you had any luck on using the DAB module from Klyde with your other headunit?
It would not be that the module are using a usb port along with an analog input??
It wont fit on my JY unit because it lacks the 2 sockets on the back that KLD units have. Theres no usb on it, just those 2 plugs and an SMA for the antenna.
DAB App
Is the DAB App Version from the Fileserver the only one you have? It has to work with the DAB+ Module from Klyde. Does anyone know, how to use the app? At the first start I found national stations (like ENERGY) AND local stations (like hr). I'm living in Germany, so sorry for my bad english. After a factory reset, I only get the national stations, either with L-Band turned on or off. What can I do to get all stations?

I just have the DAB app that appeared in "OEM" app in June and the DAB (2) app that I put on the fileserver, just go through all the settings and play about with it. Are you sure its not the signal ? Do you have a boosted antenna ?
I have tested all settings with no luck. I don't think that it is the antenna because I am using the stock antenna wich is delivered with the DAB+ module.
In your Fileserver I can only find the dab(2).apk. Where can I find the oem version of the app?
TL;DR Auxillary and bluetooth have much lesser quality than USB. Video links below show stereo head units that support Android USB audio with app control for the best quality connection (Spotify, Pandora, Google Play Music via USB in your car!) These are single DIN head units without AA.
For audiophiles such as myself, auxiliary cables or Bluetooth is unacceptable when connecting to my car audio system. With these methods, the phone acts as the digital to audio converter instead of the head unit thus greatly reducing sound quality on a high end system. With a USB connection, the phone only acts as storage and a music player while the head unit acts as the DCA.
Finding head units that have a compatible USB connection to android devices has been very difficult in the past. I resorted to storing all my music on an old iPod touch to get Spotify working with my car through USB. The new Android Open Accessory 2.0 is changing that.
I have found a few of youtube videos demonstrating Android USB plug and play connection with two different modes:
App control: Spotify, Pandora, iHeartRadio, Google Play Music ect. (Yes SPOTIFY!!!)
MTP: browse local music files.
- supports basic functions such as play/pause/next/prev
- should work with android version 4.1+
- beware: some head unit models require a software update which can be installed through usb.
- warning: these videos only show connection to nexus phones, meaning if your phone isn't running google edition AOSP, it could cause problems.
- note: AOA 2.0 is different than the android audio update with lollipop, which was meant to allow connection to a separate external DCA via USB OTG.
- more info about the 3 types of android USB connection found in this thread: http://forums.androidcentral.com/an...3-will-android-l-allow-usb-audio-out-car.html

There are undoubtedly many other head units that support AOA 2.0, but these have video proof!
I have a Nexus 5x, I just ordered the Pioneer DEH-X3800UI for $75 on Amazon.
Ill have the head unit installed within the next week, and will give an update.
Hello Android USB Audio! Goodbye and good riddance iPod touch!
I'm hoping somebody has bought one of these headunits & can confirm how well it works.
Does it essentially work like a USB DAC would & all audio including waze, Poweramp youtube all play through the headunit and speakers?
edit: I found the answer, yes ALL audio goes through the headunit. See here:
go to 5:15
https://www.youtube.com/watch?v=ZyOh32a-cY8
TL;DR probably All head units with AOA 2.0 support that on the market right now have a clicking/micro pausing problem.
Sorry for a late response, I had to do some research, as explained below.
Now its time for the good, the bad, and the ugly!
The Good: The head unit preformed as promised, it was simple plug and play to rout all audio from the phone to the car speakers, matching Ipod via USB quality. Spotify, Youtube, Soundcloud, and even Maps navigation all worked.
The Bad: Every 5-30 seconds there is a quick high pitch clicking sound accompanied by a micro pause of the audio of about a quarter of a second. This clicking only happens with a constant audio stream such as a song, not with something brief such as a Maps navigation direction, nor when the phone is plugged in without any audio being streamed. Sometimes I would get lucky and the audio would be perfect for a couple minutes, once even for a couple songs. But when it does happen, the clicking is quite loud and high pitch and with micro pause it is easily noticeable during a normal song. I had 3 friends come listen to my "new setup" to ask them how it sounds, and all 3 of them noticed it. Unacceptable for an audiophile such as myself, so i did some research and conducted some experiments.
The Ugly: I devised a way to easily notice and keep track of the clicks. I played a low constant tone of a 40hz sine wave at high volume which made the abrupt high pitch clicks very loud (and annoying) in contrast to the low constant tone, and it made the micro pauses very obvious due to the interruption of the bass. With my phone I would hear random clicks every 5-30 seconds. I then tested 5 different android phones with various ROMs and about 10 different usb cords and many combinations of them. Clicking was reliably random. I changed kernel settings on some of the phones to see if the cpu performance was effecting it. I tried various apps such as sound about and the pioneer music app. Nothing changed.
I then went to an electronics store that had 8 head units available in store that supported Android Open Accessory 2.0. all hooked up for listening and ready for testing. There were 3 Pioneers, 2 JVC's, and 3 Kenwoods. ALL of them had the clicking problem. The Pioneers were the worst: the most frequent and loud clicks, followed closely behind by the JVC's. The Kenwoods, had clicks every 30 seconds to 2 minutes, and were about 40% less loud. I suspect that with the Kenwood head unit the average person might not be able to detect the clicking and micro pauses during a normal song, but I know i could in my high end system, especially after all this nonsense i would be passively listening for it.
Conclusion: I suspect that there is either a fundamental problem with Android Open Accessory 2.0 that causes the clicking, or the stereo manufacturers are cutting corners somewhere, or maybe some incompatibility issue with the software. I just don't know. I tried to do more research but I have found nothing online about this specific issue.

I tried various apps such as sound about and the pioneer music app. Nothing changed.
I then went to an electronics store that had 8 head units available in store that supported Android Open Accessory 2.0. all hooked up for listening and ready for testing. There were 3 Pioneers, 2 JVC's, and 3 Kenwoods. ALL of them had the clicking problem. The Pioneers were the worst: the most frequent and loud clicks, followed closely behind by the JVC's. The Kenwoods, had clicks every 30 seconds to 2 minutes, and were about 40% less loud. I suspect that with the Kenwood head unit the average person might not be able to detect the clicking and micro pauses during a normal song, but I know i could in my high end system, especially after all this nonsense i would be passively listening for it.
Conclusion: I suspect that there is either a fundamental problem with Android Open Accessory 2.0 that causes the clicking, or the stereo manufacturers are cutting corners somewhere, or maybe some incompatibility issue with the software. I just don't know. I tried to do more research but I have found nothing online about this specific issue.

ok wow, I'll try to get to a shop soon& test my tablet.
I'm really hoping I can use an OTG cable + hub & then go into one of these headunits. I need the hub in my car for rear camera & SSD media drive.

I do actually have a Hifimediy u2 USB DAC.
I'm hoping to go from nexus 7>otg>hub>straight into the AOA 2.0 receiver.
If not my backup will be the USB DAC into a Pioneer 80prs.
Anybody have input?
What would be better in terms of sound quality?
-The aoa 2.0 allows me USB streaming digital into HU
vs
-USB DAC (by passing internal DAC) into Pioneer 80PRS (Amazing Sound quality HU for 250$) but this will have to be done via AUX.
Does the fact I have to use AUX even matter? will it degrade the quality?

I know using straight AUX from the device tremendously reduces sound quality due to the device acting as a crappy DAC, then sending the audio signal through the AUX to the unit.
But if it goes to a separate DAC then through AUX, i dont know. I would like to find out also

I've posted on a few car audio boards. Nobody seems to ask this in the past becasue everybody in the past used ipod via usb. Bluetooth if they dont care about quality.
I think in most cases like you said, the response was negative to using AUX but thats because of the headphone jack / internal DAC as you know.
I'm just curious like you to know how much we would loose by using AUX. Maybe some will say it's because of another D/A conversion but can anybody really tell? I'll wait for some answers.
In regards to the OP, if you have a high end car system, why not shell out for an Android Auto head unit? The data for music is sent via USB I'm pretty sure as I can tell a clear difference between my Kenwood's BT vs AA.
(I suppose flac files are an issue but you mentioned spotify, which does have AA support)

Double DIN radio are more for toys. They don't have the EQ or processing power of single DIN's.

Uh... I never said that he "needed" AA. I am certainly not an expert on head units and am not a claimed audiophile but based on what the requirements were, I don't see a reason why AA can't work. It is simpler to setup, includes spotify support, as well as a more cohesive and unified interface. Based on the issues getting audio over USB to work I think AA is a good alternative.
I'm not sure how DDs have less processing power but if you need such a thing, just add a DSP. I personally am fine with just an amp. Seems very extreme to claim them as toys. I wouldn't be so prejudiced...

Main reasons:
-Touch screens are difficult to operate while driving
-My car would need modifications to install a double din
-And of course the price. I do have a quite high end system, but It is extremely cost efficient.
I believe AA is a waste of money if all you care about is sound quality because the cheapest solution for usb quality app radio is still just a $70 head unit and a used ipod touch for $50.
This is what I had before I heard about these new head units that still cost $70 but allow usb connection to android with aoa so I could potentially get rid of the ipod and just use my phone, but it hasn't worked out so far lol.

AOA only supports 44.1 KHz sampling rate. Maybe a re-sampling issue.
To test I'd try 44.1 source material on a device that is native 44.1.
Note also that Google considers AOA deprecated and discourages it's further use. Very few people used it so Google may not bother fixing bugs, and it may not be a part of their Compatibility Test Suite..

Indeed that is a good point. My unit basically cost the same as what I paid for my speakers and amp. I wish you luck on finding a solution!
With more research i concluded that in the following connection:
Device > USB OTG > DAC > AUX > Head Unit
The aux will not effect the sound quality, but this connection will only be on par with USB if the external DAC is capable of grater or equal sound quality of the Head Unit DAC, AND if the AUX cable is of good quality as well.
That being said, i also concluded that depending on the bit rate of the audio, and the quality of your hardware, bluetooth quality might be indistinguishable from USB, especially in the sound environment of a car. But you would have to test that yourself.
I will be going for the external DAC

Hey Everyone!
I'm looking for a good, reasonably priced, double-din head unit that supports Android Auto for my 1995 Volvo 850 Turbo and am looking for some advice/suggestions.
All the car audio sites (Crutchfield, etc.) show that you can't install a double-din in the 850, but that's only due to two small plastic lips in the console from the original stereo that can easily be removed with a dremel.
I was looking at the JBL CP100, but that still isn't available yet (for who knows how long). I would like to get something with a reasonably modern feature-set and UI, and I've generally had good experiences with standard Kenwood receivers (I currently have a KDC-BT562U installed), but I'm not particularly picky.
I have an Xperia Z5 so Android Auto is a must (obviously), but also having Apple CarPlay functionality could be useful as I sometimes share the car with iPhone users, as long as it doesn't add on to the cost. Also, having a good standard Bluetooth connection option for relatively short drives that wouldn't require the full AA experience, but having the ability to just listen to music and make/receive phone calls is important.
I'm looking for something below around $450, but if that's not possible, I would like the get the least-expensive product that's not too much of a compromise.
Any input would be appreciated as I (obviously) have pretty much zero understanding of car-related things.
Thanks-in-advance!

I was planning on installing an Android tablet, like the Nexus 7, as a car headunit. But the major issue for me is the sound. The sound from the headphone jack isn't the clearest. USB audio has its draw backs, mainly when you have a lot of apps open and memory usage is high, the sound gets choppy. I have been looking at these android car radios but I have not been able to find anything with a more elaborate sound processing section. I'm talking about filtering such as low and high pass capability, bass filtering, loudness levels, etc. A lot of them has the EQ app but that doesn't do any frequency filtering. You can buy a separate active crossover unit, but that's not plug and play, and you still have to somehow figure out how to connect one with RCA inputs to the tablet which probably needs some other kind of interface, more stuff to buy. So for now, I'm staying with a real car headunit until I find one that will suit my needs.
You can find the Pioneer 4100NXT for around 450-500. I think it is first rate and does both CarPlay and Android Auto from two different USB ports. It also has an optical drive and SD card slot so there is plenty of room for media if you set it up for both Android Auto and CarPlay. I don't think any of the other third party units are this versatile (the JBL CLEARLY isn't).
I am very happy with the audio from this. Independent adjustable crossover points for both front and rear, phase control for each speaker, and two custom presets on the EQ, in addition to three or four best seat in the house (vehicle) settings. Honestly, the only thing that is missing is what's missing in Android Auto (Waze, Dash, etc.).

If you like Android and want the ability to mod your device, you could look at numerous number of double din android units for China. I purchase a unit from Erisin that was specifically design for my car but they also sell standard double din units. They are expandable so you can add dab, dvr, mic, etc and can mirror a connected android / apple phone. Also support Bluetooth. Worth a look
I am actually looking at that right now. Thanks for the suggestion. Looks like these Android car radios still have ways to go when it comes to audio options. I am very particular about how my system sounds and an EQ alone is not enough to clean up audio sound for me. Thanks again.

I am not sure what other options you're looking for. The crossovers have adjustable frequency and slope on both sides of the crossover point, preamp outs for all 5 channels, and manual or automatically measured (kinda pointless in most cars though) set points for time alignment.
If you've had a Pioneer headunit, you'll know what I'm talking about. All these Android radios have an EQ section but doesn't have high pass filter for the front and rear speakers and doesn't have low pass for subs. So you got low frequencies going to the midrange and tweeters which will distort the sound. These options are built in to most Pioneer headunits.

Super new here, I tried searching for my problem but I may just be blind. Thanks in advance for taking the time to help out.
I've got an 06' BMW with a witson android head unit.
The issue I'm having is Bluetooth music audio quality. Oddly enough Bluetooth calling isn't a problem. The upper range of sound is distorting. Don't know if this makes a difference or not, it's connecting to an iphone *hides under table. If I listen to the radio or to a cd (like it's 1997 or something) I don't hear the issue.
I've gone into the factory settings, and adjusted the BT volume up and down and found no change. I've changed all of the volume options, and found no change. I've tried changing the amplifier settings as well and have found no change.
MCU version MCTB-KYD-V2.77

Have you tried factory settings, and turning down BT master volume. Mine was set well above the others, which could cause issues when in higher volume ranges.
Yes, in fact I was super excited when I searched and found the factory settings code, and that the bt adjustment was in there. It was set to +18 I've since set it to 0 and saw no improvement.
I guess my question is this
Clearly, a setting isn't going to fix this, should I just install a new Bluetooth app, or is the Bluetooth app essential to the operating system and I should just install a new operating system??
HI
I have erisin 2046 and my bluetooth music is scratching hard.. quality is very bad
set the master volume down already in factorysettings (126) but nothing changed.
Sounds like a firmware update is required... maybe to android 5.1? If only people answered more often about doing them... (I have no idea how)
I have two units (MTCB KLD, MTCD KGL) and an old clarion HU with bluetooth.
This problem exists all three units. It's not a firmware problem, problably MCU related issue.
I was digging many forums about this, but I cannot find solution.
I have a MTCD unit which is functioning well but the BT streaming quality is quiet bad.
It's quiet easy to do an A and B comparison with our android units so it will be obvious but if you didn't know, you'd think it's ok.
I just think bluetooth streaming quality is generally bad if you don't use APTX
probably there is a problem with smartphone. When I using android one, there is no distorting in upper range. However, when I use iPhone SE, it's hard to hear distorting sound and quality is really bad.
I have the same problem. Very bad sounding, upper range is distorted. I've tried 3rd party Bluetooth apps, but it doesn't recognize the unit as having Bluetooth. Probably cause the Bluetooth chip is in the MCU, and is not actually part of the android software. That's my guess.
Does anyone know if a Bluetooth dongle to the USB will work? I have a spare one laying around.

The bluetooth module connected to the MCU.
The MCU provide the Bluetooth audio stream to the Android OS.
The Bluetooth app can control the BT module through the MCU.
So there isn't direct link between the android OS and the bluetooth module.

Audio streaming over Bluetooth App from my iPhone (say from Pandora) is noticeably worse quality than using an app on the HU (say, Pandora App on HU). Do not have this problem streaming to other HUs (like the one built into the Prius) or my previous GTA Kit.
Which is your favorite color phone case?
After watching a few YouTube videos I now understand that the dual feature of the Note 8 Bluetooth has nothing to do with Bluetooth 5.
From what I've learned, Bluetooth 5 is simply a combination of Classic Bluetooth (2 & 3) coupled with Extended Bluetooth (high range with lesser throughput), which does NOT mean you can expect to crash n your speaker in the house from the garden.
In other words, for the DUAL Bluetooth feature on the Note 8, it would appear that there are in fact two separate BT reciever / transmitters.
Can anyone verify this?
Also, if this is true, how likely will it be that either a software update or an app will be able to take advantage of this, and split stereo channels to two separate Bluetooth speakers, thus giving true stereo sound in the home?

Why I don't know, maybe it does have two BT chips in it. I'm going to guess it does. The delay sucks though for sure.
Meh... I'll take any answer I can get at this point just get the discussion going. Can't believe this hasn't been a major discussion topic yet, and I can't find anything about what I'm asking on the web.
The delay can be remedied by changing placement of the phone between the devices. In other words, from what I've read / heard, no matter how different the two speakers are, there's a theoretical distance between each one that is the ideal placement for the phone where they'll be no lag between the two. I've done this in my own house. I relocated a small table in the foyer to get optimum placement between the dining room and living room speakers.
I have yet to try this with identical speakers to check if midway between them is ideal placement for the phone.

My problem isn't the latency it's the dang volumes. Even with the setting. Can't think of it as I haven't tried in a while. But one of my speakers are as quiet as can be the other is blazing loud. I could never get them to even nearly match...
Surely it's only got one Bluetooth chip just allows more than 1 connection.
No different than having your speakers and a watch connected at the same time 2.
Just 2 audio streams at once
What hasn't Bluetooth allowed more than once bt device gonna had before as long as they used different profiles
I have several speakers, and also two of the same model by the same brand, and until now, I could never get then to play at the same time.
Maybe I should just bitter the bullet and buy a system that splits the stereo channel between two speakers after.
Dual Bluetooth feature means that you can connect with two Bluetooth audio devices at same time and music on the phone will be played simultaneously on the both devices. Left audio channel on the first connected, Right audio channel on second connected.
Switch "Dual audio" via 3dots Bluetooth menu.
Only first device can control (pause/play/next/previos) phone's player.
There is no need both devices to be same brand/model.
Bluetooth version of devices is also not important.
All version are backwards compatible with previous versions. So if your phone is v5, first speaker v4, second v2, so all communications will be on v2.
Even v1 Bluetooth support up to 8 devices multiple (serial) connections. One phone connected to 7 others and gaming multiplayer (Nokia N-gage) . But just now manufacturer deside to make two (audio channels) connection.
ChoSmile, I'm failing to understand...
Are you saying they are already separated into left and right audio channels??
dual Bluetooth has nothing to do with channel separation; all it does is allow 2 devices to be connected to your phone via Bluetooth at the same time, listening to the same exact audio stream

Why I don't know, maybe it does have two BT chips in it. I'm going to guess it does. The delay sucks though for sure.

Meh... I'll take any answer I can get at this point just get the discussion going. Can't believe this hasn't been a major discussion topic yet, and I can't find anything about what I'm asking on the web.
The delay can be remedied by changing placement of the phone between the devices. In other words, from what I've read / heard, no matter how different the two speakers are, there's a theoretical distance between each one that is the ideal placement for the phone where they'll be no lag between the two. I've done this in my own house. I relocated a small table in the foyer to get optimum placement between the dining room and living room speakers.
I have yet to try this with identical speakers to check if midway between them is ideal placement for the phone.

I play music through poweramp to 2 phillips bt speakers that can connect together anyways. But it's a pain to connect them like that so I just connect them with the dual bt the phone uses. I know what your talking about with the delay so right away I figured out that after they are paired and music starts playing (delayed of course) I simply force close poweramp, go back in and hit play and..... No delay
I'm using 2x Sony Srs-XB10s which natively support stereo pairing themselves, and I dual audio to a Marley with a cheap iPod dock, bluetooth adapter.
There's a ~1s delay from the Sony's when they're in native-stereo mode.
There's ~0.3s delay when they're attached singularly over Bluetooth. This fluctuates, but usually grows to ~0.8s over 2 minutes, then resets.
It's upsetting the audio can't be delayed per-device manually.
I love the technology though and it excited me I could in theory have 5.1 with this solution (Marley is almost a 2.1) but alas it's not mature enough.
Keenly interested in the progress of this feature! Saves the manufacturer having to implement it, though Sony's, despite the bigger delay, is very very simple and obviously there's no delay between their own 2 speakers.
