Hello everyone.
I recently bought a android head unit.
I have additional speakers in rear and they are louder than the front ones. When i had older radio i could set it up by balance betwen front and back.
Now this option is missing in sound settings (i dont have that icon in top right corner).
My system info:
Android: haoling_00009_V001_20191128
OS: 9.1 XY Auto: 3.1 (8227L)
DDR: 1G Flash: 16G
CPU: A7 1.3GHz
MCU: 3.1 (8227L)
Can i downgrade or upgrade to get this option?
If yes, which firmware shloud i use?
Thanks in advance for your help

I bought it from second hand, so I don't have contact to him.
Try to search in Settings the option of Sound and Balance. It's there.

I just bought a fairly cheap Chinese Head unit for my 2005 Accord. The hardware is not bad but the software has some issues. The manual is as always horrible and the seller has no info on Software Updates or a link to a Website that has them.
Does anyone have a link the stock Firmware just in case I decide to mess with the unit and mess thinks up? I am more afraid with loosing the Climate Controls and making the car dangerous to drive (no heat, AC etc) in bad weather conditions.
In addition is there a link where I can get the latest version or a better version of the App? If I flash a different firmware do I need to change the CAN parameters to match my Vehicle so that the Climate Control works properly?
The Specs are the following:
Android: YT9217B_00002_V004_20190815
Abdroid OS: Android 9.1
XY AUTO: 3.1 (8227L)
CAN BUS: 3.0 (8227L)
DDR: 2GB Flash: 32G
CPU: A& 1.3Ghz x 4
MCU: 3.1 (8227L)
In case I flash a non stock firmware do I have to reprogram all the Climate buttons of the unit?
Or maybe it would be better to root the unit and install CarWebGuru or Agama?
Thanks for the info

Give the search a try, seems there's info on: YT9217B
What is the best way to root this device? I basically want to upgrade the radio app and just use a 3rd party home app. I there a recommended method for OS 9?
Did you catch some progress? I have the same unit on the Passat car. All is working quite well - we need "simmple" root, but for this head unit and android 9.1 is not abvailable. We don´t need any big update. I´m looking for FM RDS unlock, more CANBUS aplication, contacts APK and music improvement - thats all.
you should check out this thread here.

Hello I have an unbranded headunit from eBay. I’ve already contacted the seller and tried my best to scour these threads but that hasn’t helped. I have no control of my subwoofer port on the back of there unit. The upgraded firmware that they show on the advertisement has an equalizer that includes sub, lo, mid, and hi but I have a 4 band with hz. I’m looking for the right firmware/mcu version
What my unit says now.

Cpu: a7
Display: 1024x600
MCU: 3.1
What I’m looking for it to say
Android: YT_9217c_00005_V003_20181222 HIFI
Not important
Amplifier: ac7315 mos Bile duct 45wx4
Mcu: HW8227L 3.3- SWO-1.3
If that’s not possible I at least would like the most current update for this device or if I can flash another mcu firmware or software from a different device to it that would work too. I just want/need something better than what I’m working with now.
. Thanks in advance for any help.
Hi Guys,
Its been a long time since i posted a thread in XDA.
Now i am back with my Android Headunit.
I got a cheap Android headunit from a local dealer.

There is no clarity and life to music.

Hi everybody!
I recently bought a 8227L_demo unbranded Chinese android stereo.
Unfortunately, I can’t control the screen on the dashboard because the simulated buttons are not working…so I can't access the clock and time settings on my display...
Below you can see all my system information (unfortunately I can't attach picture because I'm a newbie).
I have a CANBUS Raise psa-rz-15 device.
Steering Wheel Controls are regularly functioning.
My car is a Citroen C3 (year 2008).
I set the Peugeot 307 (2002-2013) Canbus protocol; however, I tried all the available protocols one by one but nothing changes.
Anybody else has the same problem? What can I do to solve?
Maybe with a firmware update?
Thanks again in advance

Go to -> Car setting -> General
Touch the gear top right.
Enter 8888
Change CanBus Settings to Peugeot 307
Hi!
I already set the Peugeot 307 (2002-2013) Canbus protocol and I tried all the available protocols one by one but nothing changes...

Hi,
Do you solve your problem ? i have the same for my 308 car with PSA-RZ-15 CANBUS ?
Which canbus do you have ?
Hi guys,
I have a Chinese Android headunit with the 8227L_Demo chip and the fader-balance is not working. I have the option but when I move the dot around the car image, the sound still plays on all 4 speakers. Also, the EQ settings doesn't seems to change anything. The other bug I have is there a big gap/jump in the volume between 17 and 18 and the sound mute for half a second when I switch from 17 to 18 and vice versa.
Anyone experienced something like that ?
As I can't upload any image here I write all the info of my headunit.

me too, same problem. my unit is Blaupunkt key largo 970 but CPU-Z and some other in system hidden settings confirm that this unit is alps_ 8227L_Demo.
can you share your Equalizer.apk app?
plz help me i cant use sound fader , the sound too loud behind me and it disturbing mz
Hello Guys, I don't have any solution, but I have the same issue. Fader doesnt work. As far as I know, this is not because of the HU but the Harness. I have a JBL System and I had to buy an extra harness which doesnt allow me to use FADER.
My 2 cents.

can you show us picture please
I'm afraid guys, there is no solution. The reason it doesn't work is that your unit does not have a dedicated audio chip. Older units all had it, like YT9216, YT9217, YT9218, and even (older) YT9213AJ. If you buy Android 8.x or 9.x then the audio chip will be present.
See the pictures below explaining the issue.
The audio chip is TDA7729 (TDA7719 , CSC37033 , SCS37534).
Now there is a fix but it requires advanced soldering skills and a proper setup.
Sorry to be the bearer of bad news.
