Does your car support Android Auto? Then get yourself an adapter which performs a straight conversion from Wireless to wired Android Auto and not from Wireless Android Auto to wired CarPlay.

@CiNcH83
my car doesn't support android auto
that's why I purchased the data adapter

[CiNcH83]

I really believe that this conversion only works for the most basic HUs.

There are no questions about the transformation itself, everything works well!
The device can even output full HD.
The problem is the aspect ratio

i have the same problem on My Geely Coolray , when set the resolution to 1280X480 or 1920X720 it freeze
i have 12.3 inch screen

when freeze it show as below

i have to set a wrong resolution to work but the aspect ratio will be wrong.

you can validate the dimension to the resolution using
http://fredfred.net/screen-size-comparer/
and calculate the aspect ratio and DPI using
https://www.sven.de/dpi/

screen1 is your screen
screen 2 is my screen

I am still not sure what is the official resolution of my screen either 1920720 or 1280480
my car Aspect ratio: 2.67:1
the stretched images above is actually 1280*720
