Fader-Balance not working on 8227L_Demo Head unit - Android Head-Units

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.
Android: YT9213AJ_00011_V001_20200330
Android OS: 9.1
XY AUTO: 3.2 (8227L)
CAN PRO: 3.1 (8227L)
DDR: 1G
FLASH: 16G
CPU: A7 1.3Ghz x 4
Display: 1024*600
MCU: 3.1 (8227L)

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.

No, all apps work for now pretty good.
I can't find a way to fix the mic of the stereo though
And change the home screen to make it more convenient.
I tried agama luncher but it get stuck almost every time it turns on
Try factory settings, Code 8888, others >>> mic sensitivity. Work ed for me. Alternativ use mtk engeneer from market

Questions regarding a YT9217B Android Head unit XY Auto (8227L) YT9217B_00002_V004_20

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
Mike

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.

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.

Unknown Android headunit. Who helps?

Hi guys,
I have owned different MTCD headunits (all px 3/5).
For my new car I ordered a 64/4 headunit but it seems like it's a different chipset etc.
As I have a few problems with is and the seller isn't respnding (yet) I'll hope you can help me identify the unit so I can update firmware/mcu etc
Cons:
Biggest issue: GPS is not working. Because of that the time and date are off. If adjusting it manually it stays on the time and date from where the unit gets to sleepmode and won't adjust untill manual adjustment.
I have a annoying humming sound in the OEM subwoofer. It wasn't there with the Kenwood headunit that was installed before this one. Still can't solve it. It also humms when the RCA aren't attached so it seems a power input issue to the amp of the subwoofer. Still figuring out what to do about it.
Pros:
It seems to have wireless Android Auto besides wireless Carplay. It was not advertised but when I put on my hotspot from my mobile, it autostarts Android Auto on the headunit. Very nice!
Bought on Hipzo store (Aliexpress).
CPU INFO: UIS8581A (Octa 1.6GHZ)
MCU: 2021.12.10 15:04:26 NOR_53_L6315_G23P48F64_V:1.0
Android 11 (not sure, seems like Android 10 because of buildnumber)
buildnumber: QP1A.190711.020
System info: APP 1024x600 2021-12-11
Any help is appreciated.
Hello,
Could you share the findings about this head unit?
I have the same head unit, except for CPU and display resolution. I am still trying to understand what is the version which is compatible with this head unit.
Any info is well appreciated.
UIS7862 FYT based unit

Land Cruiser cooling fan issue 5760b head unit

I just installed the following H.U.
Android: YT5760B_00002_V001
Android os: Android_12.0 XY AUDIO: J1.73 (AC825
CAN BUS: 10.0.3 (disconnect) 2-2009
DDR: 8G
FLASH: 128G
CORE: 8 (64bit) FREQ: 2.5GHz
Radio: AM+FM+RDS
Display: 1280*720(mipi)
MCU1: 0.7 (AC8259) Audio decoder: ADI
DSP: ADI-1701
Everything is working fine except that the car ventilation system is at full speed in the back of the car. I cant seem to be able to control it from the dash oars (car dashboard).
I gave seen a thread with someone mentioning it but after hours of search i cant find that comment/thread anymore.
As it is my first H.U, i just need some idea about this issue. Probably the canbus? Does the canbus message (disconnect) means it is not connected or does this message has nothing to do with the fact it is correctly installed?
P.S the sound Quality is simply amazing!!
Tx in advance
I fixed it by changing the Canbus settings.
