If you're asking how to connect a rear camera to the navigation system's display, then here's what you need to know.
First, click here
to view a picture of the rear of the display unit. The 4-pin connector is what you're after. The top right pin is #1 and is for rear-video-in. The bottom left pin is #4 and you connect your video cable's shield to that. The system uses #4 to detect whether a rear video camera is connected.
Once that's done, the system will automatically switch the display to the rear video source whenever you put the transmission in reverse, even overriding the the intro/agreement screens.
