Steering Wheel Control Adapter for BMW / Mini ACV SWC 42XBM009-0

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 functions may be limited or replaced by others. Compare the displayed wiring connectors with the connectors in your vehicle and ensure they match both technically and visually. Verify whether any of the listed OEM radios were originally installed. Before final installation, check the vehicle's functionality, system settings, and proper operation of the steering wheel control (SWC).
