Steering Wheel Control Adapter for BMW / Mini ACV SWC 42XBM005-0

Maintain the original radio control functions from the steering wheel when replacing the factory 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 those in your vehicle to ensure they match both technically and visually. Check if any of the listed OEM radios were originally installed. Verify vehicle functionality, system settings, and proper steering wheel control operation (SWC) before final installation.
