AW: For vehicles with an RCA output for the rear-view camera signal, the direct connection at device is available. For example for VW and SKODA vehicles, a RVC signal output coming off the Quadlock main harness provides a direct connection to the RCA rear camera input of the CORE device. See pages 74 to 76 in the main device manual. For other vehicles, 3rd party aftermarket interfaces are available, which can be quite expensive depending on the vehicle make and model as well as the interface electronics.
