I’ve installed arch manually a few times. The last time I did it I had issues with my nvidia gpu and plasma glitching out drawing weird lines on the screen. I got tired of trying to fix it and went back to windows for a while. Figured I’d try crunchyos to see if their setup resolved that and it did. And now that it’s installed there’s no reason to uninstall.

Mapping and navigation still work but only update when you update the car. You lose access to real time traffic and the lte network.
