To connect a Dometic PerfectView camera to your multimedia display all you need is a Dometic control box and the RVSC2 truck adapter. The Dometic PerfectView RVSC2 is a custom fit for the original SCANIA Orlaco monitor. Depending on the selected switch box it is compatible with all Dometic cameras. For installation of the CAM 55 NAV, you won't even need the control box. The adapter will suffice.
