[Android Head-Units] stealthrt:
I have the following type of Head unit that I really have not seen anything about when speaking about firmware and upgrading it to Android 9.

At this point I really do not know which firmware I can use for this unit since it does not tell me the MCU. I have downloaded a LOT of firmware's but most of them say for head unit "PXx" MCU which again i have no idea which one I have if any of those at all.

So it would be great if someone could point me to the firmware that my head unit needs in order for me to update to "real" Android 9! :)
