Adding multiple cameras to the factory screen is no longer an issue. This LVDS camera switching interface is intended for use on 8" factory screens to enable a single camera input or add up to 4 cameras. This interface can be programmed to automatically activate the camera inputs based on turn signal or reverse triggers via the vehicle's CAN Bus communication. The Rear Video Assistant (RVA) option can be used to keep a camera active during the duration of a trip, allowing the driver to monitor a trailer hitch, baby in the backseat, or rear cargo.
