[Android Head-Units] TheMatrix1010:
Hello

First at all, a big thank you for the research done and the explanations (complicated to understand for me :) )

From what I understood I have to find a way to interface the LIN bus with my Android HU? Right?

From this link, I can read the information of the LIN bus from an Arduino. The question is how can I figure out how to interface my HU with the Arduino? Do you have any information about the link with the HU (CAN BUS or other)?

The use of a product already manufactured is relatively expensive: [IMG="LIN bus to CAN bus"]https://i.postimg.cc/mrRRFSgk/Manufactured-LIN-Bus-Converter-to-CAN-BUS.jpg[/IMG]

Regarding the secret menu, I have access via a code to the HU configuration menu:

And finally, my idea of a generic system is to decorate the "UC" and "display" to allow for easier physical integration. I could then use any touch screen size and put the "UC" elsewhere in the vehicle. the interconnection between the "UC" and the "display" would be on a more robust connector (HMDI, DisplayPort, etc...)

Another advantage, the screen could be more "fine" than those offered by dealers and better integrate into cars.

That's why I'm looking for a PX3/PX5/PX6 card without a screen.

NB: I found with the file explorer an interesting log file
