CD PLAYER WITH CHANGER, FUNCTION - GF82.64-P-3113-02GI
Controlling CD player
The CD player with changer (in trunk) (A2/6) is controlled by the radio and navigation module (A2/56)via
the digital data bus (D2B).
The CD player generates reports on the following operating conditions:
No magazine in CD changer
Magazine assignment (only with music CD)
Number of current CD
Number of current title
List of occupied slots (CDs)
Title number per disc
Current operating state (acoustic playback of radio signals, pause, etc.)
The messages are stored on the digital data bus D2B ) and interpreted by the radio and navigation module
(A2/56) .
CD playback
The audio data is stored digitally on the CD-ROM . The audio CD is driven by a motor in the CD-player with
changer (in trunk) (A2/6) .

The laser-optical device scans the non-labeled side of the rotating CDwithout making contact and converts the
digital optical signals into electrical signals. Small interruptions in the data flow of the laser optics caused by
scratches or contamination on the audio CD are compensated by the D/A converter supplementing the missing
values .
The electrical signals are then decoded in the CD player with changer (in trunk) (A2/6) and transmitted via
the digital data bus ( D2B ) to the radio and navigation module (A2/56) via the audio signal processing or
when the sound amplifier (A2/13) (code 810) is installed to the loudspeakers.
Jumps and interruptions during playback
On bad roads or in the event of heavy vibrations , jumps and interruptions can occur during playback. In
such cases do not start CD mode until better road conditions are present.
In the event of wet weather conditions and strong deviations in the ambient temperatures moisture can collect in
the CD player housing (condensation formation). This could also lead to malfunctions in the playback. In such
cases provide for sufficient ventilation of the CD player and the trunk.

The digital components of the radio and navigation unit (A2/56)are interlinked via the digital data bus
( D2B ). Control data, audio signals and other information are transmitted between the various system
components via the digital data bus ( D2B ) Since some of the individual components operate with various data
formats or place different requirements on the transmission speed and transmission security, various bus
systems are installed.
