2. Connect the camera's ground cable (black wire) to the car's reverse light negative (-) or chassis ground.
3. Connect the camera's video RCA cable to the "CAM IN" (or similar) RCA input on the back of the radio.

4.4 Steering Wheel Control Connection

To use your car's original steering wheel controls, you need to connect the radio's KEY1 (and KEY2 if available) wires to your vehicle's steering wheel control wires. This function usually requires manual configuration in the radio's settings menu after wiring. This feature is not compatible with cars that require a CANbus decoder.
