3.3 Steering Wheel Control (SWC)
The method for connecting 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, go to "SteeringWheel Key" in the manual match settings to activate the button functions.
- With CANBUS Decoder: Connect the CANBUS before powering on the machine. Navigate to Apps > Settings > Factory Settings (password: 8888/8317) > Vehicle > Automotive type. Select the brand of the CANBUS decoder and then the matching model and year according to your vehicle's specifications.
