4.3 Steering Wheel Control (SWC)
The method for activating steering wheel controls 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, navigate to the unit's settings (Car Settings -> Factory (000000) -> SWC) to manually match and activate the button functions.
- With CANBUS Decoder: Connect the CANBUS decoder before powering on the radio. Then, go to the unit's settings (Car Settings -> Factory (000000) -> CarType Setting). Select the brand of the CANBUS decoder and then choose the matching model and year to ensure proper SWC functionality.
