MODEL 164 with CODE (494) USA version with CODE (528) HIGH Class USA with CODE (530) COMAND APS USA (with navigation system) up to Model Year 2008 

The signal processing required for the volume and tone settings is accomplished by the COMAND operating, display and control unit (A40/3). Two versions are available:

If the vehicle is also equipped with the amplifier for the sound system (N40/3) (Sound System (code 810)) it provides for final application of the audio signals.

Audio sources are: 

Service sources include: 

Volume setting 

The volume can be adjusted with the push/rotary switch for "ON" and "OFF" and volume control on the COMAND operating, display and control unit for each audio source set as well as for voice output for navigation and telephone.

The volume can also be controlled with the + and - buttons on the multifunction steering wheel when set to specific functions and volume control (S111s1)

Automatic volume control 

A speed-dependent volume control and volume control which adapts to the interior noise in the vehicle are available depending on the vehicle equipment.

Mute 

If the user presses the "MUTE" function key, the audio source currently audible is muted. If the CD changer (A2/6) or internal CD drive is in operation, it is switched to pause. The muting can be initiated automatically.

When the "MUTE" function key is pressed a second time, or the pushbutton/rotary switch for the volume is actuated, muting is canceled.

The volume of any active audio source is automatically muted during a telephone call to ensure minimum distortion to the voice input from the user on the hands-free system microphone group (A67b1).

If the "MUTE" function key is pressed in the navigation mode, the voice guidance is switched off. Voice guidance can be switched back on with the "RPT" function key.

If the "Mute" function key is pressed in the satellite radio mode, muting is accomplished until the "Mute" button is pressed again or the system is switched over to another audio source. Pressing the pushbutton/rotary switch for the volume also cancels the muting mode.

If an emergency call is triggered by the TELE AID emergency call system (code 359), the audio sources and service sources are automatically muted.

Tone setting 

The COMAND operating, display and control unit allows manual tone settings for each audio source.

The tone settings include:

Treble and bass 

The display for adjusting the treble and bass appears when the "Bass" or "Treble" soft key on the right multifunction key strip (audio function) is pressed.

The bass and treble can be adjusted with the "left" and "right" arrow keys on the joystick. The set value is stored when the "OK" key on the joystick is pressed. If the operator waits until the display changes, the value is also stored.

Differentiated treble and bass control is possible with the following features:

Balance/fader 

The balance and fader settings are possible with the following features:

When the "Bal/Fad" soft key on the right multifunction key strip (audio function) is pressed, the display for adjusting the balance and fader appears. The display shows a horizontal and vertical line which intercept. The horizontal line represents the fader and the vertical line, the balance.

The balance can be set with the "left" and "right" arrow keys on the joystick and the fader with the "up" and "down" arrow keys. The balance and fader can be adjusted simultaneously with the "/" and "\\" buttons.

Setting is stored when the "OK" button on the joystick or the "Back" soft key in the right multifunction key strip is pressed. If the operator waits until the display changes, the value is also stored.

IMPORTANT The setting applies for the current function, however, it is not automatically stored for the other functions.
