Theory Of Operation

The Camera is activated when the ignition switch is in the RUN position. The Fused Run Relay Output circuit supplies power to the camera. The camera sends a video signal (std. NTSC i.e. TV) to the Radio using a Low Voltage Digital Signal (LVDS) cable, which displays on the Radio screen. The screen toggles functions displaying only one kind of image at a time. And in reverse, the rear camera has priority.
