Q:

I can't see the reverse screen when my car is in reverse.

A:

1.Please make sure your car is equipped with a reversing camera or a subsequent retrofitted reversing camera.
If it was retrofitted, please select: Aftermarket Camera,
If your car comes with a reversing camera, please select: OEM Camera.

Routes:Settings-System-Camera Selection

2.If selecting the correct camera still doesn't work, go to Factory Mode Gear Selection 1 2 3 and try them all.
