- If it is OE camera, just need to choose "OEM camera" in camera type in android setting(System->Camera Selection->OEM Camera).
- If it is aftermarket camera, need to choose "aftermarket camera" in camera type in android setting , BMW manual gear car need to go into factory setting to change it from Automatic to Manual.
- For wiring aftermarket camera, check camera connection in the paper in the package.（bmw manual and automatic gearbox wiring is different）
- If still not work: please try all option in Factory setting->Vehicle->gear Selection-gear 1, 2, 3 to check which one makes the camera work
