Steering wheel button control adapter for Citroën / Peugeot / Toyota ACV SWC 42XPG016-0

Preserve the original steering wheel radio control functions 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 the connectors in your vehicle and ensure they match both technically and visually. Check whether one of the listed OEM head units was originally installed. Before final installation, verify vehicle functionality, system settings and correct operation of the steering wheel control (SWC).
