Circuit/System Description

When the transmission is placed into REVERSE, a 12 volt signal is sent to the rear vision camera indicating that camera operation is requested. Ignition voltage and ground are supplied to the rear vision camera. The rear vision camera sends video information to the radio through a video signal + and a video signal - circuit. A grounded shielding also wraps the video signal circuits to reduce electronic interference which may degrade the video signal and cause a distorted or otherwise degraded image.
