I've noticed an issue with the reverse camera app having focus stolen by a pip app.
I have Spotify as a pip app, but sometimes it takes a while to load. I'll often be in the middle of reversing, and it will quit out of the reverse app, going back to the homescreen showing Spotify doing something. I'll then need to shift out and back into reverse to reactivate the reverse camera app.
Also seem to be missing LPF for subwoofer?
