Hi all
I'm having a bit of an issue with my Android Auto setup.
I've just gotten over the black screen issue (I was missing a microphone, duh!) but now my screen is rotated 90 degrees and completely off centre.
I'm running a WaveShare 7.9 inch 1280x400 display, running WITH the fkms driver (got that to work nicely), a RPI 4 8GB, 16GB SD Card, 5V 3A psu, UGreen USB Soundcard, Techkey bluetooth dongle and my phone is a Xiaomi Poco X3 Pro.
Basically what happens is this: I plug in my phone with the USB (haven't gotten wireless to work yet), I click next on my phone and it says to look at my car screen to continue. The google screen is completely to the right side of the display and rotated 90 degrees. I can just about see the google logo and the text underneath it, although its very blurry. I managed to get the desktop and OAP enviroment to be rotated landscapewise using the screen setup tool built into PiOS
