The adapter is suitable for connecting video accessories such as a rear view camera, DVD player, VCR, or DVB-T tuner. The Fakra connector of the adapter cable connects to the navigation system, and video can be connected via the RCA port. Please verify whether the navigation system has a rear view camera input.
