Amplifier identification for Joying Units - VW Passat 2012 B7 Europe variant - Android Auto General

Hi , I am planning to buy a Joying Android 5.1.1 Intel 2GB Headunit but i am not sure if i have an amplifier in my car.
The car was bought as a " used car " so i have no idea if the previous owner had installed any amplifier.
How can i find out firstly if i have an amplifier and secondly the make/location of this amplifier.
I am not an expert in sound quality so if my question seems silly, bear with me
Car : VW Passat 2012 B7 estate model (Europe) with RNS310 headunit
PS :Google was not at all helpful , hence turning to our forum for answers
Thanks in advance !

Hi, anybody? ?

You do not need an amplifier to use this radio.
In order to find an amplifier, have a look at your battery, see if there is a big 6 or 8 guage power wire attached, these are usually related to amplifiers, if so, follow this wire to your amplifier.
Also, check for a blue wire coming from the back of your stereo. It will be labelled AMP REMOTE.
It will also have some AV cables coming from the rear of your radio. You can follow these to the amp also.
Usually check under the seats or in the boot.

I noticed that Octa Core PX5 VW head unit come out . it seems that the cpu will be fast than before . you can visit their new website for check .

The Intel units are better than the px5. Get the Intel instead of px5.

Witch head unit for my 2012 Ford Focus?

I'm a little bit confused...
I've bin looking for a good aftermarket head unit for my 2012 Ford Focus.
I found a few devices witch are based on the S160 platform like roadnavi.
Also a device witch is marked as 5.1.1 <LINK> witch seams to be on a mtcd base.
Im not sure if there is a devices available on a mtcb base for my car model.
What i read on xda, mtcb is the most popular an mod friendly device, mtcd is maybe to new on the market.
Have any of you guys a recommendation for me? Maybe one have the same car?
Thanks, Stefan
hello,
i have a 2013 ford focus.
Sad to see that here is no answer since 1 year.
iam looking for a replacement head unit too
have you found a headunit?
regards Christoph
I bought my unit from that company I have a 2011 Focus. Been working great for more than a year now.
It supports steering wheel controls, OEM reverse sensors, displaying which doors are open including boot. I also bought the boot handle camera and wired that up.
The only downsides are BT audio isn't the best, so I play all my music off USB.
And it seems like the PX3 units drain a little power when the car is off but I've always been able to start my car so probably not a big issue.
I flashed my unit with a KD rom as it looks nicer and updated my MCU to the latest version for KGL.
Here are a few head units for you to look at:

Recommendations on current Android Headunits

Hi Guys
I've just passed my current car containing my MTCD headunit to my wife, having bought myself a new car. Its a vehicle specific unit so will be staying in my wifes car.
There are no vehicle specif units for my new car, so am looking at standard double din options. To be honest, I've never been overly happy with the MTCD unit, its the first gen version with 5.1.1 the crappy PX3 Rockchip SOC and 1 gig of RAM. I've finally got it working acceptably using Malaysks ROM and Micro Gapps, but dont really want to stick another one of these in the new car!
There are a few more options available these days, PX5 units with better Rockchip SOC and 2GB RAM, the Intel Sofia Units, some other varients and I am also looking at an Android Auto head Unit from JVC as these are coming down in price.
Important things for me are:
Bluetooth Hands free
Radio (not fussed about DAB)
Sat Nav / Maps
Reversing Cam
Music
Listening to Audiobooks, probably doesnt need to be listed, but its important to me!
ODB stuff is nice (but not so important)
Lastly, the performance needs to be acceptable, I dont care if its not blazing fast, but we all know how slow some of these units are!
With all this in mind, what do people suggest looking at currently?
Many Thanks.
Josh
Also interested.
Have done lots of reading on the PX5 vs Sofia but haven't come to a conclusion yet.
I too am in the market, I got an old Dashlinq 4 in my BRZ running Android 4.1.1 and would love something that can actually run somewhat smoothly and keep pace with current apps now. Really would like something with at least Android 6.0 and 2GB of ram. Other than that needs to be Toyota Universal 6.2 inch double din size.
If the vehicle allows it, get an Android 7.x, with a high res IPS display, they are flooding these in the android HU market in china, but models are limits to popular car models.

Eonon, Xtrons or Joying?

Hi All,
Im thinking of buying a new head unit for my BMW E90, are there any preferences over these brands? Im swaying towards the Eonon GA7165/GA8165 but i believe most of these units are all the same but branded differently?
<--Update-->
Right so after carefully considering everything for 2 years I finally bought one!
I've just purchased the Xtrons PE9890BIPL
https://xtrons.co.uk/bmw-3-series-android-8-0-pe9890bipl
It is on offer for just £239.99 which to me was a steal as second hand units (if you can find one) tend to sell for around £150+ because most people paid £300ish.
it has a beefy specced system of an Octa Core PX5 processor with 4GB RAM and a 32GB ROM running Android 8.0. This unit also has a big 9" screen at the expense of losing a DVD drive and some physical buttons (all of which can be used from your own steering wheel controls) but they offer the same spec with a smaller screen and contains the physical buttons if you'd prefer the physical buttons and DVD drive.
the newer head units running Android 9.0 aren't as good, currently offering a quad core PX35 processor (same x64 bit architecture but runs more efficient) and only 2GB RAM and 16GB ROM so it's a downgrade really.
Then of course we move onto the brilliant XDA forum for custom ROMS, and it just so happens they've already managed to get Android 9.0 onto these PX5 units
So I chose Xtrons because from what I've read most companies buy these units from the same supplier and brand them leaving other factors to be considered, for me xtrons is UK based so next day delivery, plus clearence prices, they also offered the beefier head unit, support seems okay (some chaps hasd ssues with steering wheel functions not working after locking and getting back into car, long story short they sent people new looms and sorted) and then on top of this XDA developers providing custom ROMS which can fix a lot of the common issues. I'll provide another update when it comes on Monday
at the moment
8-core-px5 - Dasaita > All because of the different (stand-alone BT and WiFi chips)
4-Core-px3 - IMHO the only differnce is the OS. 7.1 has no custom roms yet, so yo probably have a bloated OS
difference at both to consider: AMP chip TDA7388 or TDA7850, clear recomindation is the TDA7850 because ist has way more power and sounds clearer and more crisp

Hey I'm new here.
Is the selection of AMP chip important ? Seems there's very few manufacturers using TDA7850.
The few that do use TDA7850 seem lots more expensive. Is this normal ?

1) BT and Wifi are going to be on the *same* chip, so don't need to pluralize that.
2) The positioning of that particular RF chip (whether it be on the SoM or the host board) doesn't *technically* matter. The downside to being on the host board is typically that the reseller may have a bigger part in writing software that interfaces with it, and reseller written software is always a very bad thing.
3) Intel Sofia units also have the wifibt and GPS chips on the SoM.
Even with the wifibt on the SoM, the resellers *still* manage to mess it up, however, it may be somewhat easier to clean up in this case.

I think it may have to do mainly with your needs and expectations.
Neither is going to satisfy anyone who self-identifies as an "audiophile".
I think the main differences are that the 7850 is slightly more powerful (4x50 vs 4x45 watt), and is ok with 2 ohm speakers where the 7388 is 4 ohm only.

Which make and model has the 7850 chip? I've just had a look at the Eonons, Xtrons and Joying units for the E90 and the most I have found is 4x48w and all the rest are the same 4x45w.
Not sure which chip mine got but I do have the Octacore GA7165A and I'm really happy with it just a few setup things I need to figure out. I also installed Viper4Android which improves the sound greatly only issue I'm facing is it does not apply to the MTC radio.

Probably because the radio analog output never touches the CPU. It goes RADIO --> BD37xxx --> amplifier --> speakers.
The BD37xxx is an audio processor/mixer. Bunch of analog inputs, bunch of analog outputs, i2c control from either the MCU or SoC depending in which vendor it is.

Hi mate,
Good to hear that Viper4Android works on the GA7165A model, so you've not experienced any other issues? On a YouTube video I've read various things such as Audio quality being poor through Spotify which is one of the main things I'd want, and also phone calls sounding muffled, though I assume that's probably down to the positioning of the Mic itself. What sound system do you have as well mate, is it stock or upgraded?

I’ve got the stock sound system of a 2006 E91 I have installed Spotify but I haven’t used it yet still waiting for my mifi device but I’ll give it a shot maybe tomorrow and let you know.
In terms of Bluetooth / phone Bluetooth music is very good and also works through Viper4Android for the phone function itself I’ve only used the internal mic so far and that is a bit quiet but I’ll install the external mic later in the hope that it will improve the volume issue.
One thing I did have was V4A wouldn’t start automatically until I installed it as a system app now or does that just fine and from a sound quality perspective it is not worse than the default Prof. Head unit if anything I would say better since I can set a more granular sound set-up ( I like deep bass when the radio is not too loud just like the loudness feature on other stereos).
Not sure where you live if anywhere near southwest London feel free to pm me and we can meet for a coffee and you can have a look at it
@mrsweet1991 Have not yet tinkered with the mic but I did try Spotify for you and can report it works just fine I left the Spotify EQ off and instead use V4A and the sound quality is as good as an MP3 on the USB.
Hope that helps.
Have now installed the external mic however I had to disconnect the internal mic to get good quality I might go ahead and solder the external mic onto the internal port so I can use that for OK Google etc as well but with external mic and internal disconnected the quality is good.
How can i root the ga8165 and install xposed framework?

I recently purchased this unit (GA7165A)and installed it.
If you purchased this unit how do you like it so far?
By the way I have a L7 AMP (fiber) and had to do a bit of research to figure out a few functional work around.

Hi Mate,
Been such a long time since I've been on here, I just wanted to say a big thanks for the information it's good to know. I'm hoping one day I might get a break from fixing things on the car and actually get to stick an eonon unit in! Last time I here the 7165a was the best out and now there's a 8165a lol

Hi mate, I've not had a chance to buy one yet.. I seem to end up fixing the bloody car all the time haha. Walked in for an MOT and come out with a failure for a snapped rear spring and a couple of other minor things.. Starting to get back on track now though, so I take it you have the logic 7 system? Mines just the basic system with underseat subs so should be easier to setup but less rewarding on the sound quality side haha.
Also interested in buying a unit for my E90, just not sure how to pick a unit and know that im getting one of the more reliable manufacturers with stable software? Anyone have experience with the Eonon 8165A? seems like the best deal..

Can any GA8615a owners vouch for the sound quality? Is it any worse than the stock HU?

Newbies head unit buyers guide

I scanned thru several of these forums looking at the stickies in particular plus a few searches. However, I didn't find anything that would guide the selection of my 1st Android head unit. In particular, I am looking for the pros and cons of each type (Intel vs PX3 vs PX5, etc), as well as preferred manufacturers. I can fit a universal 2DIN in the dash with slight alterations. I would like to mod the unit so significant community involvement in customization is very important to me vs. having the latest and greatest thing out there. I want to hook up the unit to my Canbus so I can capture the steering wheel signals in my 2012 Ram 1500. I think that my truck has an external amp, but that it uses speaker-level signals vs. line level to drive. I have a factory externally amplified sub in the back. What other features are discriminators when trying to select the best unit? Thanks in advance!

I've had a bad experience with android (bought from Erisin) my unit died after only 6 months use (PX3 board) I then bought a PX5 board which only lasted a few weeks - when working the PX3 was ok - PX5 was faster - the unit I got seems impossible to get into recovery thus far. Erisin won't provide any support as they know it's too late for me to complain to Ebay or Paypal. I liked the android but I would look for a unit that has good support and is easy to get into recovery should things go wrong. I also have another car which has Windows system (Xtrons) but with built in DAB which apart from minor glitches has been good but is a little restricted with some software I would like to use.

Looking for 2din head unit with fastboot and 4g sim connection

I have greate head unit in my toyota ractis that is cheap and work well with fast boot [joying brand]
My friend have another head unit that have sim card internet support but it's boot time is very long [Ownice brand]
I'm looking for head unit that will have also fast boot [that I couldn't find in Owince devices] and 3G\4G [the more the better]
thanks
I would think that this would get more views in the general android head unit forum rather than the MTCB sub forum. Also I think that looking for a new MTCB device is not wise at this moment there seems to be better newer things out there. Pretty much it seems there are two choices PX5 type devices or Atoto which uses mediatek. I have been reading many pages in the android head unit forums the last few weeks. I think I will settle for a atoto a6y pro. The other unit I think I may buy is the v600 dasaita version of the px5. I have a 2017 mitsubishi outlander GT with factory rockford amp and 360 camera. PX5 units have the advantage of custom roms and newer android. ATOTO units have older android but better preamp and better bluetooth. As far as your cellular needs this will most likely require a dongle with any unit that you buy. Any android ready usb dongle should work. Get a unit that has more usb ports and probably USB 2.0 is better for cellular dongle. The atoto has the best boot times from what I can research but it seems that many of the youtube videos of the atoto units are sponsored so I take those with a grain of salt. Also the amazon reviews although good link all models of the atoto in the reviews so that you have to manually read if the review is for the pro versions. I would only buy a atoto pro with the upgraded amp and qualcom bluetooth. The atoto a6y pro also seems to have fakra Z gps plug which for me looks like I can use my factory antennas for gps.
