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

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.

Fader-Balance not working on 8227L_Demo Head unit

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.

PX5 MTCE Android 10 - WiFi Connectivity / Stability Issues

Hi All,
I'm bit new to the world of Android Head Unit who recently purchased a PX5 Android 10 head unit for my Peugeot 407.
After installation everything works fine expect for one problem. WiFi doesn't work.
If I turn ON the WiFi, it finds my network, connects to it, and then immediately the WiFi turns OFF. It keeps turning ON and OFF in loop.
So reached out to my seller who provided a firmware file using which I upgraded my unit successfully. But no luck. WiFi still has the same problem. It keeps turning ON and OFF in continuous loop.
Head Unit Specifications
Car: Peugeot 407
Unit: PX5
CPU: Octa-core Cortex-A53 @1.5G
Memory: 4GB
Storage: 64GB
MCU Version: MTCE_MX2_V3.60_1
Kernel Version: 4.19.111+
Build Number: rk368-userdebug 10 [email protected] eng.hct2.20200909.085823
Bluetooth Module: WQ_RF210 (as pre-selected in the Factory settings in the head unit)
I've attached a video of my symptoms as well. Please can you have a look and advise / point me in the right direction to fix this WiFi problem.
I spent time tracking down the seller for firmware update because I'm not sure how to identify the specific model / manufacturer etc of the unit.
Any advise on how to identify the finer details associated with the Head Unit Model would also be very helpful.
Thank you.

Did you check the wifi antenna?
I have a 407 - (2007) - does your head unit allow for aircon and heating/ventilation controls and all the canbus functions?
my orange dispaly is failing so thought I'd install one of these instead
Do you have a link for the one you bought? I've been looking for octacore - most are quad
Thanks
Found some interesting info here

I can't find my exact seller listing but below link is a similar eBay listing for the same model I have got.
Peugeot 407 Android 10 PX5 4-64
Yes, it integrates seamlessly with canbus / climate control etc. It comes with a canbus connector. There's an option to connect reverse camera if you want to. But you have to buy the reverse camera separately. Other than that there's a GPS antenna, built in and extra microphones for phone calls, memory card slot, USB slots etc.
I wouldn't recommend any sellers for this kind of after market head units as they are all sold / shipped by overseas / international sellers. There's always a risk with this type purchases. So proceed with caution. If you end up getting a good unit, the risk is well rewarded. Your Pegueot gets a major upgrade.
All the best!

Thanks!
I've been looking at these ones.
Still undecided
Might just get a new mfd screen & keep using my phone!

Have you guys found any solutions to your canbus problems with Peugeot 407? I lost my automatic headlights / daylights which I'd love to have back. Have you encountered and solved other issues with Android head units?
I can't either enable some car functions from car app from head unit (automatic lights, rear wiper, parking radar etc.). Can you see the outside / inside temperatures of the car somewhere? My A/C works somehow (responses like it should to physical buttons, but I bet it has mechanical faults instead communication problems with head unit).

Hello there,
See this workaround.
Custom ROMs such as @Hal9k_ 's Mod V5 have workarounds for this under Mod settings. In that ROM, go to Mod settings, select "Hardware settings" and toggle on the "Reset USB devices when booting or waking up".

Help with Chinese android headunit

So I bought this head unit from Amazon specific for my 2009 Toyota Corolla. It has the fake android 10 but want to flash a working rom. Right now my head unit keeps closing apps and nothing works at this point. Even tried to reset it using the little pin hole on the front of the head unit but doesn’t do anything at all. Please help! All I need to know is which rom to flash to this head unit.
Specs of my head unit
Android: YT9216BF_00007_V004
Android OS: 10.1
XY Auto: 3.4 (8227L)
Can Pro: 3.1 (8227L)
DDR: 2G
Flash: 32G
CPU: A7 1.3GHz x 4
Radio: NXP6856
Display: 1024 x 600
MCU: 3.1 (8227L)

If it doesn't do anything when pushing reset you should return the head unit. The reset button is hardware related and has nothing to do with the firmware so I think there is a technical defect.
Buy a head unit you can find some information here on xda if you expect to get help from other users. Don't buy exotic unknown devices.

For Toyota Corolla Junsun V1 is available. No the best head unit but also not the worst. Or a PX6 could be a good choice.

I need help with Chinese Headunit using iPhone. I did factory reset and now nothing works. PLEASE HELP ME. I am not tech savvy on these units.

8227L, YT9213A HELP PLEASE

Hi guys,
I have a Chinese Android head unit i bought last year. Please don't laugh, it was good at the time until I received it.
It's not too bad of a unit in all but it has issues.
I have started following Iceblue1980's guide all in one SUPER MOD, but the backup part was hard to follow and My device was not backed up. Now I have flashed the new firmware within the guide but my side buttons now don't work and I can't get the TWRP to work. I get a error (pmt changed for the rom it must be downloaded please select format all + download scene and try again) and on the left side of SP flash tool is has my unit as mt8127.
can anybody help me out please?
i would like a nice and smooth, useable android unit.
hopefully one where i can listen to my music without it playing up and starting off at near full volume when it wants to, where my phone works properly via the head unit with a contact list from my phone in a decent list order (like android auto) and my messages will show up on the head uint also.
my mate has a sony double din stereo and he can call and message on his head unit and voice control also. if i could get that good from this unit i would be amazed.
i like the Viper4Android setup and the launcher on Iceblue1980's guide.
any help would be great.
My Head Unit:
YT9213A_00009_V001_20200312, OS: android 9.1, XY Auto: 3.2, CAN Pro: 3.0 (8227L), DDR: 2G, Flash 32G, CPU: A7 1.3GHz X 4, Display: 1024*600, MCU: 3.1 (8227L)
thanks in advance guys.
