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.

The CD player with changer (in luggage compartment) (A2/6) is operated via the COMAND operating, display and control unit (A40/3) and actuated via the Digital Data Bus (D2B). The audio signals of the CD changer are likewise transmitted via the Digital Data Bus (D2B) and amplified via the COMAND operating, display and control unit (A40/3). With code (810) Sound system, the signals are amplified by the sound amplifier (A2/13).

Acoustic emission is carried out via the vehicle's loudspeaker system.

On vehicles as of 1.9.03, the audio gateway control unit (N93/1) is also installed as an interface between the Controller Area Network bus class B (interior) (CAN-B) and the Media Oriented System Transport (MOST). The audio signals are then sent to the audio gateway control unit (N93/1) and output via the vehicle speakers.

Only 12 cm CDs may be used; do not use any 8 cm CD adapters.

The CD player with changer (in trunk) (A2/6) offers the following functions:

SCAN functionn
The tracks of one CD or the 1st track of all CDs in the magazine are played for 8 seconds. After this has been run through completely, the scan function is automatically terminated.
Track selection
The tracks of a CD can be selected via a rocker or a numerical keypad.
Random function
All the titles on a CD or the entire CD magazine are played in accordance with the random principle.
Repeat function
Alternatively a title, a CD or the entire CD magazine is repeated.
Fast forward or reverse (music search)
The music played is audible during fast forward or reverse. Certain parts of a title can therefore be specifically played or skipped.

CD title allocation, function

Each CD contains a permanently stored table of contents, the so called Table of Contents (TOC) record.

The COMAND operating, display and control unit (A40/3) clearly recognizes the respective CD based on this entry and is able to automatically name it after the one-time user allocation of the track (even if the CD is subsequently inserted in another CD magazine). The TOC record additionally contains information regarding the number of titles on a CD and the CD's total playing time. The COMAND operating, display and control unit (A40/3) has an integrated CD disk drive which is used for loading the navigation data or for playing audio CDs (no audio CDs can be played during navigation mode).

On vehicles as of 1.9.02, it is possible to listen to audio CDs during navigation mode. Only the navigation CD has to be loaded previously.
