The signal processing required for the volume and tone settings is accomplished by the COMAND operating, display and control unit (A40/3). If the vehicle is additionally equipped with the amplifier for sound system (N40/3) (sound system, code 810), this amplifier provides the final amplification of the audio signals.

Volume 

A different volume setting is possible for the navigation and for the telephone. A shared setting applies to the other modes. The set volume is stored automatically by the COMAND operating, display and control unit for the currently active mode.

Volume setting 

The volume can be adjusted with the rotary pushbutton of the COMAND operating, display and controller unit for each of the selected audio sources as well as for the voice output for navigation, voice output for voice control system (VCS [SBS]), and telephone.

The volume can also be controlled via the multifunction steering wheel (MFL) using the buttons + and - for setting specific functions and volume control (S111s1).
