When replacing the factory radio with an aftermarket radio, the original functions of the steering wheel remote control must be retained. Depending on the vehicle equipment and the scope of functions and software of the retrofit device, individual operating functions may be omitted or replaced by other functions. Compare the adapter plugs shown with the plugs in your vehicle and make sure that they match visually and technically. Also check whether one of the specified original factory radios is installed in your vehicle. Before final installation, check the vehicle's operation, vehicle settings and the steering wheel remote control for functionality.
