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.
