Protótipo da Central multimídia Android, montando a mesma no meu VW UP!.

Since I started this project, I was wondering if someone already done something similar with this particulary hardware.
First problems envolved with Android Auto or Android 12 with the hardware:
Hardware:
Orange Pi 5 Plus (8Gb Ram - 256Gb Emmc)
Touch Screen 7'' with HDMI Input + Touch USB Support working (out-of-box)
AV2HDMI (Upscaler 1080p or 720p) Working with HDMI IN APP
Adaptor 12v to 5v 3A with two USB ports to powering on the Orange Pi 5 Plus and AV2HDMI
Teramps Sound amplifier with 400RMS/4 or 100RMS per channel
UBLOX USB GPS Module (Works only in Mock Location with GPS Connector)
Let's get started. First thing I had an issue is with GPS Module, it's shows information in Android, but the system does not use this Module as Internal GPS and I need to use GPS Connector App to get things working, using as USB GPS from Ublox in configuration and set mock location with GPS Connector App, you will need to activate Developer mode to do that.
Now my GPS works like a charm, but when boot Up the OPI5+, need to launch the app again and gives OK to use the GPS Module again, that is a problem too.
With the Screen 7'' I previous had , with HDMI In and no 30 pins connector to the board of orange pi, the cables is a mess in my car, One cable HDMI to use the Screen and another to use HDMI Input of this OPI5+ Board. I buy another Screen with connection with flat cables to OP5+ Board needs 10 days to arrive from China mainland.
The Adaptor 12v to 5v 3A is amazing, even when I start engine, the OP5+ does not shutdown.
I need more research in a way to made my OP5+ Boots Up when I switch the ignition and shutdown without cut the power as It does now.
Another issue is the AV2HDMI that uses another port USB from Adaptor 12v to 5V 3A. I only get image on screen opening the HDMI IN App that came with OP5+ Android Image pre-installed. But no lucky with a way to made it opens automaticaly when it has signal from Cam (AV Cam to HDMI module).
So that's it, I hope we can change knolodges in this little project of an DIY Home Made Android 12 Head Unit.
Best regards,
