Adapter for steering wheel control mercedes cls, e, slk amplifier most.

When replacing the factory radio with an aftermarket radio, the original functions of the steering wheel remote control must be retained. Depending on the vehicle's equipment and the scope of functions and software of the retrofit device, individual operating functions may be omitted or replaced by other functions. Compare the adapter plugs shown with those in your vehicle and ensure they match visually and technically. Also check whether one of the listed original factory radios is installed in your vehicle. Before final installation, check vehicle operation, vehicle settings and the steering wheel remote control for functionality.
