Product Description The adapter cable allows you to connect a video signal to a navigation system with video input on Fakra socket. Adapter is suitable for connecting video accessories such as rear camera, DVD, VCR, DVBT , etc. Fakra connector of the adapter cable is connected to the navigation system. Video can now be connected to the RCA. Anticipation is to examine in each case whether the Navi has a connection for the rear camera. It is a green Fakra connector on the back. To my knowledge, the Navis this connection as standard (even if the car has no camera).
