Introduction
Rear view camera is a nice feature to have, especially if rear window is tinted. In this page we review rear view cameras and wiring. To see the picture on COMAND screen multimedia interface must be installed. Alternatively, a cheap third party LCD monitor can be purchased.
Wiring
Wire should go along the red positive wire.
