CD playback
The audio data is digitally stored on the CD ROM. The audio CD in the CD player is driven by a motor. The laser optics scan the unwritten side of the
rotating CD without touching it and convert the digital optical signals into electronic signals. Minor playback faults caused by scratches or soiling on the
Audio CD are interpolated by the D/A converter and therefore compensated for. The electronic signals are subsequently decoded in the CD changer
(A2/6) and passed via the MOST to the radio (A2), radio control panel and navigation unit (A2/56) or COMAND operating, display and control unit
(A40/3) and the audio gateway control unit (N93/1). All control data such as input errors and the response from the CD changer (A2/6) are shown on the
display of the radio (A2), the radio control panel and navigation unit (A2/56) or the COMAND operating, display and control unit (A40/3).
The audio gateway control unit (N93/1) receives the audio data via the MOST. The digitized information is converted to analog here and passed to the
vehicle speakers.
Jumps and interruptions during playback
When driving on poor roads and during strong vibrations it may be that jumps and interruptions occur during playback. In such cases, CD operation must
wait until the road conditions improve.
If there are large fluctuations in the ambient temperature, moisture can accumulate in the housing of the CD changer (A2/6) due to condensation. This
may also lead to faults occurring during playback. In such cases it should be ensured that the CD changer (A2/6) is adequately ventilated.
