I'm generally happy with my head unit but i want to ask you is there any updated software-firmware for my unit which i can install?
If i use default media player application i can use steering and other controls, but if i use any other media player i can't use them. Is there anything i can do about this ?
Can i change ringtone of my head unit?
When i'm making a bluetooth call, sound is bit bad, Is there anything i can do about this?
Thanks.
Note: This is my first post, so i'm sorry if i created thread in wrong section.

i cant really change the style, the "main screen" got a big ass ugly clock and if i change my hotkey apps in the lower bar, they dont stay there after turning off my car.
this are my main issuse with this head unit.
is this a problem with my device in general or is it a problem with the android rom?
and if it is so, can i change it easy and wich rom should i flash?
down here i got some pictures with more information about my device and a pic of my "main screen"

Questions to start with Android HU (Mods, Rooting, CFW)

Hi,
this is my first post here on XDA Developers and I'm new to Android. This HU is my first device with Android for my Smart car.
So I bought this unit from Aliexpress.
Model: PX5
Android Version: 9
Build: rk3368-userdebug 9 PQ2A. 190305.002 20190628.103151 test-keys
Kernel Version: 4.4.167 ....... #98 Thu Jan 27 17:21:19 CST 2019
MCU Version: MTCE_GS_V3.17_3 ....... Jun 21 2019 20:14:31
CPU: Octa-Core Cortex-A53 @ 1.5 G
RAM: 4 GB
So my biggest goal is to get rid of ads in Youtube. I tried Lucky Patcher but it requieres Root access. So I googled a bit and found out about Kingroot and installed it. After installation rooting my device failed. I also tried a how-to from this forum LINK but when I open 1. Disable DM-Verity.bat and enter my IP it always says "Disable DM-Verity...error: device '(null)' not found". I don't know what to do here.
Further I want to get the latest update on this HU. After I install it in my car I don't want to take it out anymore to experiment. What I need to download? I saw here some CFW but I don't know yet if they fit my device. Is there any recommended firmware I can put on this HU?
I do some research in the meantime to aquire more knowledge but this first questions would help me very much. Thank you very much for taking some time <3

I didn't find any firmware in version 2 gb, I tried to install the versions of 1 gb and it causes error
See below for details of my HU. Thank you very much for helping me (sorry for my english)

I am having the same stereo.
The model details are almost the same as you mentioned for my android stereo.
The issue with my stereo is when I do a factory reset, the system gets hung after showing the "Erasing" android icon and a dead android icon with a Blue exclamation is displayed,
Any fix for this ?

Can you help me with usb 4g dongle issue?
Hi I have made a video tutorial on how to make stock ROM backup
Hi friends,
Have you are observed overheating of touch panel of your car stereo or hangs in your Android car stereo or system not responding or application keep crashing etc.
Then this video is for you. I have done this small modification in my car.
I made a small hole on sides of AC vents such that cool air blows over the heat sink of Android car stereo and two cpu fans of 12V take power supply from same connector.
Whenever the car stereo is turned ON the fans also turn ON and blow cool air over the heat sink to keep it cool.

Bajwa ji it appears the password is Google password not unit lockscreen password.
Please try your Google account password that you may have set to protect that unit.
It is ac8227l yt9216b unit 16gb ROM version.
If that fits not work then apko factory reset karna padega. But all data will be lost forever.

Sir i could not recall password for that account. Further how to perform factory reset? bcoz screen is locked. So should i go for installation of new software. if so then plz guide how to install it...
Try to connect the unit to your computer or laptop. If somehow you can connect the unit to adb mode then factory reset can be done from recovery mode.
