Installation
Wiring the Reversing Camera
Proper wiring of the reversing camera is crucial for its functionality and to ensure optimal Bluetooth and WiFi reception. Follow these steps:
- Connect the Red Cable (1) to the positive terminal of your car's reverse light cable.
- Connect the Black Cable (2) to the negative terminal of your car's reverse light cable.
- The reverse input cable must be plugged into the unit even if the reverse camera is not being used. Failure to do so may affect Bluetooth and WiFi signal reception.

Steering Wheel Control Wiring
To enable the steering wheel control function, connect the appropriate wires from your car to the stereo unit. You will need to manually learn the steering wheel control buttons on the unit after connecting the wires.
- If your car has only one SWC wire, connect SW1 and SW2 together, then connect them to your car's SWC wire.
- If your car has two SWC lines, connect them to KEY1 and KEY2 respectively.
- Ensure the 8-pin cable is securely plugged into the radio connector. If not, steering wheel controls will not function.
