Steering Wheel Control Adapter for Alfa Romeo / Citroen / Fiat / Peugeot ACV SWC 42SAR003-0

Retain 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 those in your vehicle to ensure they match both technically and visually. Check whether one of the listed OEM radios was originally installed. Verify the vehicle's functionality, system settings, and proper operation of steering wheel control (SWC) before final installation.
