Hi, I have a 2010 with OEM display. The issue I am having is if I were to go into the secret menu > video input test, and select rear view proximity camera, then put the car in reverse, the rear view camera displays on the screen. It doesn't display if I were out of the secret menu and placing it in reverse. The Vehicle Configurations for Parking Camera states: Rear View Camera Not Fitted. Are there alternatives, other than GAP tools or dealership, to enable this as fitted?
