System Description
WARNING: This page is about a different car, the 2012 Nissan Pathfinder. However, it is still accessible from the selected car via links, so may be relevant.
When the shift selector is in the R position, the AV control unit receives camera image signals from the rear view camera and sends the camera image signals to the display unit which shows a view to the rear of the vehicle. Lines which indicate the vehicle clearance and distances are also displayed.
