AudioPilot (with Bose® sound system)
If the function is switched on, the noise level in the interior of the vehicle is monitored. Background noise is analyzed using a filter and playback of the music is automatically adapted not just in terms of volume, but also in terms of the dynamics of the overall frequency spectrum.
Vehicles with convertible tops are additionally equipped with extended sound control. This adjusts the playback of the music according to the special requirements when driving with the top down.
