Steering wheel button control adapter for Land Rover ACV SWC 42XLR013-0

Retain the original steering wheel radio control functions when replacing the factory radio with an aftermarket unit. Depending on the vehicle equipment, range of functions and the software of the newly installed head unit, some functions may be limited or replaced by others. Compare the displayed wiring connectors with the connectors in your vehicle and make sure they match both technically and visually. Check whether one of the listed OEM head units was originally installed. Before final installation verify the vehicle functionality, system settings and correct operation of the steering wheel control (SWC).
