Description

If you want to replace your factory radio with an aftermarket radio, you should make sure that you retain the original steering wheel remote control functions.

However, please note that depending on the vehicle equipment, range of functions and software of the aftermarket device, individual operating functions may be omitted or replaced by other functions.

Compare the adapter plugs shown with those in your vehicle and make sure that they match visually and technically.

Please also check whether one of the specified original factory radios was installed in your vehicle.

Before you finally install the retrofit radio, we recommend that you check the functions of your vehicle, the vehicle settings and the steering wheel remote control to ensure that everything is working properly.
