Steering Wheel Control Adapter for BMW / Mini ACV SWC 42A-1024-005-0

Maintain the original radio control functions from the steering wheel when replacing the original radio with an aftermarket unit. Depending on the vehicle's equipment, the range of functions, and the software of the newly installed radio, some control functions may be limited or changed. Compare the displayed wiring connectors with the connectors in your vehicle and ensure they match both technically and visually. Check whether one of the listed OEM radios was originally installed. Before final installation, also verify the vehicle's functionality, system settings, and correct operation of the steering wheel controls (SWC).
