Setting the loudness
"Loudness" increases the sound volume by increasing the bass and treble frequencies. This setting is especially suitable for low-volume settings and guarantees a pleasant sound.
Setting the SDV (speed-dependent volume)
The "SDV" function automatically adapts the audio playback volume depending on the vehicle's speed.
You can set adaptation of the volume to the vehicle's speed on a scale from 0 (no increase in volume) to 5 (large increase in volume).
Sound settings with BOSE® Surround Sound System
Activating "Surround" achieves a sound setting with greater spatiality.
This permits the creation of a virtual surround sound with conventional stereo sources such as CDs, radio, or MP3 formats, for example.
The function can be set separately for the individual audio sources.
The "Surround" function is generally activated with multi-channel sources such as 5.1 DVDs, for example.
The function cannot be activated for the source "AM".
Selecting "Linear" switches the PCM from a sound setting with a heavy bass (linear off) to a more neutral sound setup (linear on).
If the "AudioPilot" function is activated, the noise level in the interior of the vehicle is monitored.
Background noise is analyzed 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 an open top.
