PX5 , New trying to get steeringwheels controls to work

Hi everyone,
I am new to this whole Android radio ( I do work in IT ) and just figuring all of this out. I had some questions but where I bought the unit I have yet to get a answer. I have googled , but still have some questions and need help if anyone can help me out.
So I am still figuring everything out.
# Steering Wheel controls - The app shows the 4 buttons (vol -/+, skip f/b) but I can't program the buttons. I found online the factory settings and my code online (3368) and I see a CARBUS location but I am not sure what to do. I found a kuga setting, but that didn't work. help ??? what am I doing wrong {I see a lot of article to connect cables Key 1 and key 2 }
# Radio very weak - My old unit I was getting signal just fine and now this new unit seems weak. Anyway to increase the power to the antenna or I saw somewhere someone suggesting upgrading the MCU of the unit ? Anyone got a link
# Aux cable port- My car had a AUX and it worked fine with my old unit. Any way to use the AUX with my new android unit or install a app to allow me to use it again ?
# Upgrade - Can I update my unit and how do I do this ? What is my latest version and where are the links to stay up to date ?

Unfortunately, I have not solved it since I am afraid that I might brick the unit. If you solve this, please let me know. Thanks.

Desperate for solution

My HU specs are identical to above.
Unit started to randomly power off and on (sometimes has power to touch buttons, but screen is black).
I have been searching for 2 months to find a solution???
OR EVEN BETTER A REPLACEMENT MALAYSK ROM! Malaysk, could you please tell us what ROM we can use for this model?
Would very much appreciate your help if possible?
Thank you!

Finding MCU and reflashing (Hikity 8227l)

Hello, I am having issues with my chinese head unit. Its dropping the right audio channel. It plays out of all speakers but just the left channel. I'm hoping reflashing could solve the issue as support has been no help. Settings do not share the mcu and I have enabled developer mode. Here are the details I do have.
Model Number 8227L_demo
Android Version 9.1
Kernel Version 3.18.22
Build number android-trunk-m0.AC8227L-V1.0
This is the only info supplied by the About section in settings.

I have same issue.
Not only can I not get MCU info I cannot use letters in factory settings passwords so cannot enable ADB. Any help would be appreciated.

Hi Guys,
Is there really anyone who can help me with my problem?
I've serached in forum and found this one:
Bugs and updating firmware - 4-Core AllWinner ROM 32GB - DDR3 2GB - 1024X600
Hey, i would like to know if there is any update that i can do to get android auto / more stability for this head unit when i open google play it just bug out and crash the app. and Bluetooth tethering wont work with this as well. i hope there is...
forum.xda-developers.com
so i did it exactly what they said :
- os_opdate.zip on the usb stick
- settings en local update
- he strarted to update and then he came out with error status 7
- on the screen was a sort of text menu to power off and recovery etc but he was frozen so the only what i could do was power down.
- now when i turn my car key he goes on and i see my car logo and that's it or someth not even this - just black screen
I understand that maybe he stays in a sort of boot loop
i am planning to get him tomorrow out and try more but maybe is there someone who can provide me the good rom /mcu and tip about solution.
thx in advance
