[Q] Car stero suggestions.

Hi guys, I'm looking to upgrade the stereo head unit in my car and looking for one that best interfaces with my note in terms of both hands free calls and music streaming/control.
Does anyone have any suggestions for decent head units?
Which connection gives the best control Aux, Bluetooth or USB? (must be between BT and USB).
Would I get better control/dispaly from a SD card in the head?
Is there any head unit that will allow me to brows my music on the phone by artist/album etc, or am I stuck with folder browsing?
Will the car head unit display any details of the music being played, artist, track etc. or even album art?
I use player pro on the note for my music at the moment.
My requirements...
Blue-tooth Hands free calling and music streaming.
Remote Stalk Adapter available.
Front Aux Port.
Variable colour display if possible.
USB
SD Slot as a bonus.
1U preferable but can fit 2U if needs be.
Looking to spend up to around £300 ish.
Any ideas greatly appreciated.

You should post this on a car stereo forum site, they will probably be more able to help

Not at all, I'm looking for constructive replies from people who have some experience with using the note with car stereos. If someone has any relevant experience I'm sure they will help me. If not then nothing lost as far as I can see.

Try this and then let me know so i can buy one! But no.... It really looks promising, finally a company recognizes android needs integration like the piece if crap iPhone!

Wow! that looks like the business. I really wanted a 1u head but that may change my mind. Looks like I can find one to have a look at tomorrow so I'll report back once I have had a play.
I have also found this on the Kenwood site.....

How is the hunt?
I am using my note in the default head unit that came along with car (Ford Figo)
If you want to control the music from headunit, it better be bluetooth and not the Aux or USB.
If you use Aux, common sense says no control at all.
If you use USB, you can control the songs, but will not be able to answer or make calls with the car head unit.
Hence it is preferred only to use BT, that way the songs will get paused while you answer your calls and all the display is shared with your car audio headunit.
Hope this info helps.

Hunt ongoing but hoping to get a scent today.
Many thanks for the info,I wasn't aware of the limitations you describe. That's good to know.

For information I settled on the Kenwood KDC-BT92SD....
http://www.kenwood-electronics.co.uk/products/car/cd_receivers/cd/KDC-BT92SD/
The Pioneer looked as though it would offer a bit more and better integration with android but personaly I prefer the looks of the Kenwood. I had a play with and settled for the Kenwood as it looks good and sounds great. It plays the music on my Notes sd card no problem. And, if you install their music control app it creates a file/database on the sd card so you can browse by Title, Artist, Album, Playlist etc.
The software is realy a music player app which scans your music and created the file for browsing on your Kenwood stereo. It's not a bad effort but a bit slow and lacks some features such as an equaliser. You can set it to play through your favourite player software though so may be worth a mess with.
All in all so far very happy

Really? I had a look through the app list and it was completely dominated by iOS apps. They have half a dozen integrated navigation apps for iOS, zero for android. Same with the music mixers etc. All for iOS. There's only the basic stuff offered for android phones.
Looks a poor, 2nd rate effort wrt android from Pioneer IMO.

As long as it makes the buyer happy ...
For me i only want to listen songs from my mobile.. I switch on the native player from my mobile and use the equalizers on mobile...
Only the output is pushed to the headunit..
Fortunately since it has BT i can jump between songs from the headunit without touching the phone...

I agree it's not perefect but it'#s about the best there is for Android at the moment. At least it's a step in the right direction.
I agree with Coolkriss though, I only want handsfree and to be able to play my music from my phone. I have found the Kenwood does it pretty well both from the USB source and via BT.
My only quibble at the moment is that I can't find a way to stop it automatically switching to USB source when I plug the phone in. I often just want to charge it, connect to handsfree and carry on listening to the radio but it switches to USB as soon as I plug it in.

I would suggest charging via the 12 v USB charger. That way the head unit only does the BT job.
If you still wish to plug it to head unit, try disabling or enabling the USB debug option under settings--> developer

[Q] USB Audio Stream Pops & Clicks

Hi All,
I have an AT&T Nexus 6 and I am trying to stream USB audio out to my car stereo. When doing so I am hearing clicking and popping in the audio. I thought it was possibly a ROM/kernel issue but I am fully back to stock & locked and the problem still exists. Audio via mini stereo jack (aux) works fine of course, as does sound coming out of the phone's speakers, headphones, etc. I have tested 2 other android devices (Nexus 4 and Samsung Nexus 10) and USB audio is working perfectly fine in my car.
If anyone has any guidance on how to troubleshoot this it would be great. This is strange to me as USB audio out was added as a software update, so I find it very odd that it works on my older devices and but not the N6. If I can't get this figured out I will have to schedule an appointment at an AT&T warranty center to likely exchange my 35-day-old phone for a fecking refurb
Thanks for any help guys, cheers!

I RMA'd my Nexus 6 and the replacement behaves the exact same way. Other non-Nexus 6 devices tested work just fine.
Has anyone actually used streaming USB audio other than me?

What app are you using to stream? I tried, but do t know if my radio wont accept it or not. I know I can't read movies from my phone or flash drive.

The idea behind USB audio streaming is that you don't need to use an app. The device streams any and all audio out of the phone via USB rather than out of the speakers. This means that you can use Spotify, Youtube, Pandora, PlayerPro, etc. while connected to your car stereo via USB and have the audio in your phone played through your car speakers in lossless digital. This is a feature that was introduced in Android 4.4 but seemingly is saught out by nobody but me.
Prior to USB audio out, these were common options/solutions, all with drawbacks:
1. Plug into the headphone jack which is an analog signal prone to noise, interference, and muddy EQ.
2. Plug into USB and Android will automatically mount your phones sdcard partition the same way as USB thumb drive. This only works for playing media files that are saved directly to the phone. All other sounds/apps do not work through as the phone's audio hardware is not being used. This means no Pandora, Spotify, etc. and no controlling music from the phone. Casper, your radio is probably trying to mount your N6 this way – most car stereos do and are not expecting have a device connected that is outputting its own hardware-driven digital audio stream.
3. Bluetooth. This was the best solution as it uses the phones audio hardware and thus all audio is output the same way as the new USB out feature. The drawback to this is that bluetooth uses lossy-compression and so is lower fidelity than option #2, though A2DP has made quality far better than it once was.
If you can't already tell, I'm sort of a fidelity nazi and this is why I'm so desperate to find a solution to this issue at hand with the Nexus 6 USB audio out that noone seems to know exists.

Any update on this? I just got my Project Fi Nexus 6 and I am regretting not doing more research on the USB streaming in the car. The iPhone 6 worked flawlessly and I could change songs with my car (I just lacked good service). The car usb won't even recognize my google play albums downloaded to my phone BUT it will pull up my zedge ringtones. Every time I try to fool around with it, it just keeps looping my Mario ringtone through my car speakers lol. But seriously, any suggestions. I am so desperate.

I gave up and went with using bluetooth. Cost me another $120 in bull**** hardware that Grom Audio sells to make this "upgrade" possible. Quality is **** compared to what it could've been as well... sigh... first world problems

I have a Grom USB2 and a Galaxy S4 that I just upgraded from 4.4.1 to 5.0.1 (Goldeneye ROM). I successfully streamed USB with KitKat (Grom has a configure file that enables their unit to do this) but have been unable to do the same thing with Lollipop. I did the *#0808# thing and tried several settings but nothing has worked. Any ideas?

Viper4android/Audio Processing with AA

Is there any way to have viper process audio being routed to the navi when using Auto? Or does the file get processed by the head unit? Might be a silly question, but I've been searching the google for days and can't find any information about how AA processes audio. Nexus 6 with latest Chroma build, 7100nex

Isn't the whole purpose of doing AA is to have the headunit process the audio? I'm not certain too but given that you need to have a usb connection, I'd imagine thats how it works. It better not be via the bluetooth...

don't know for navi, but i know it processes music, in the bluetooth section of Vipr.

Does this apps can be use on my Xiaomi redmi Note 3G?

I was wondering this as well. In my current setup, simple Bluetooth to car stereo, v4a works great! But my next car will have AA, which I think uses USB as well as Bluetooth in some cases, I believe. Can anyone with v4a and AA confirm being able to use v4a via AA?

It does not work with AA.

When using AA the head unit will process the music, so it's similar to playing off of a flash drive. While I love V4A I prefer it this way because there is no gain limit to overcome like with Bluetooth or Aux.

Is this still the case? Audio volume is low with with AA and i have to increase head units volume when listening music with AA. I hoped V4A would fix this.

Bluetooth music quality

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.

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.
Sorry my bad english..

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.

USB Audio out?

Hi guys, I've noticed that when I connect my DAC to the type-c port on phone there's no audio.
Is there no sound routing through this interface?
Can it be enabled?
Thanks

I've tested only with Sony DAC from my Xperia XZ2. Maybe that one isn't compatible.

Maybe the Sony is passive, in that it passes through audio from the phones amp. The Meizu is active, it has its own DAC and Amp built in. Just a wild guess. Maybe the Xperia 1 II does not pass on audio from its built-in amp through the usb connection

USB-C audio works fine with the cable from my old Pixel 2XL. No settings needed.

I've tested using a Hidiz Sonata USB device and the USB audio player pro app and it'w working fine here.

XD05 Plus not connecting.
Doesn't seem to work with Xduoo XD05 Plus
The volume/power from the phone is barely okay for my IEMs, but it can't drive any of my headphones.
This was supposed to be an upgrade from my LGV30 (works fine with XD05) , unfortunately it's rather looking like I should have gone for a V50 or V60 instead.
I have checked in the developer options and it seems like USB Audio Routing is on by default.
Any recommendations to get it working would be appreciated.
I have just tested with my Dragonfly Black and that seems okay. At least it has sufficient power to drive most of my headphones to a reasonable volume. Still very keen to get it working with the Xduoo if I could though.
