If you want to replace your factory radio with an aftermarket radio, you should ensure that the original steering wheel remote control functions are retained.

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

Compare the illustrated plugs of the adapter with those in your vehicle and ensure that they fit visually and technically.

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

Before you permanently install the retrofit radio, we recommend that you check the functions of your vehicle, the vehicle settings, and the steering wheel remote control for functionality to ensure that everything works smoothly.
