Rear Camera: Operation
WARNING: This page is about a different car, the 2007 Jeep Grand Cherokee. However, it is still accessible from the selected car via links, so may be relevant.
The Camera is activated only when the vehicle is in reverse (by the back up lamps power feed). It sends a video signal (std. NTSC i.e. TV) to the navigation radio which displays on the navigation screen. The screen toggles functions displaying only one kind of image at a time. And in reverse, the rear camera has priority. Momentary blank screen in transition is normal operation
