Block diagram for COMAND cassette operation, illustrated with the following equipment installed : 

• Code (810) Sound system 

On vehicles as of 1.9.03, all audio signals of the audio components, voice signals as well as the signals of the navigation processor (N41/1) are transmitted via the Media Oriented System Transport (MOST).

On vehicles as of 1.9.03, the navigation processor (N41/1) is installed as a separate control unit in the left of the engine compartment.

Function 

The Compact Cassette (CC) player is integrated in the COMAND operating, display and control unit (A40/3n1). It is activated after inserting a cassette by pressing the "TAPE" button. The audio signals are amplified by the COMAND operating, display and control unit (A40/3) and directly output via the vehicle speakers.

If the vehicle is also equipped with a code (810) Sound system, the audio signals are transferred to the Digital Data Bus (D2B), amplified by the sound amplifier (A2/13) and output via the vehicle speakers.

The COMAND cassette system has:

• Autoreverse drive
• Fast forward and reverse
• Dolby B/C

  Noise suppression system for cassettes that have been recorded with Dolby B/C.

• CPS

  Track skipping and repeat function (music track search facility MTL). If the repeat function is active, "WDH" appears in the display.

• SCAN

  Play track for approx. 8 sec. and automatic fast forward to next track. If no more tracks are detected, tape is wound to end.

• BLANK-SKIP

  If the drive does not detect a sound signal on the cassette for more than 15 sec., it automatically fast forwards to the next track. If no more tracks are detected, the tape is wound to the end.

The CPS, SCAN and Blank-SKIP functions require:

• Sufficiently long breaks between the tracks (Break > approx. 3 s)
• low noise level during breaks
• Clearly recognizable track starts and ends

Cassettes with a playing time of 120 min. cannot be used.

As of 1.9.02, the Compact Cassette (CC) player in the COMAND operating, display and control unit (A40/3) is omitted. However, an additional jack socket for an AUX connection, the Walkman separation point (X39/45), is provided.
