- The third reversing control line (3) with labels and descriptions should also be connected as per the diagram.
- To find the reverse control wire on the power cord, start counting from the black wire on the power connector, and count past the third one. This is the reverse control wire.
*Note: A rear view camera is not standard and needs to be purchased separately. Contact customer support if you need assistance.
4.3. Steering Wheel Control Setting Instructions
To integrate your car's steering wheel controls:
- Without CANBUS (decoder box): If your power cord does not include a CANBUS decoder box, you can set up the learning steering wheel control buttons directly on the screen through the head unit's settings.
- With CANBUS (decoder box): If your power cable includes a CANBUS decoder box, you will need to set up CANBUS to decode the original steering wheel control. This step typically requires entering the factory settings. Please contact customer support for detailed guidance.
4.4. CANBUS Decoder Box Instructions
The CANBUS decoder box enables communication between your car's original systems and the head unit, allowing features like steering wheel controls and original car information display.

- If your power cord does not include CANBUS, you can disregard this section.
- CANBUS needs to be set up correctly to function. Contact customer support for guidance on setting up CANBUS for decoding original car information.
- When using CANBUS, ensure the wire is connected correctly. Do not plug the connector that connects CANBUS into the back connector of the main unit. You only need to connect the 8P connector; otherwise, the screen may not work.
Important Note:
- Please plug in the correct connector according to the guide. Plugging in the wrong connector may prevent the screen from working.
- If the screen does not turn on, check if the fuse is blown. A blown fuse indicates a potential wiring issue or short circuit. The fuse acts as a protective measure.
