The unit supports steering wheel controls for convenience and safety. The setup method depends on whether your vehicle has a CANbus decoder.
- Without CANbus Decoder: Connect the plugs or the steering wheel control wires (Key1/Key2) in the power cable to the corresponding port or wire of your original car. Then, go to 'steeringwheelkey' in the settings and manually match to activate the button function.
- With CANbus Decoder: Connect the CANbus before powering on the machine. Then, follow this path: Apps -> Settings -> Factory settings (1234) -> CAN Settings. Select the brand of the CANbus decoder and then the matching model and year according to the actual situation to make SWC work properly.
