Beschreibung

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

Please note, however, that depending on the vehicle equipment, range 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 make sure they fit 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 your vehicle's functions, vehicle settings and steering wheel remote controls to ensure that everything is working smoothly.
