DVD drive and DVD
The DVD drive of the radio (A2) reads data from the navigation DVD inserted and makes this available to the
navigation processor via the data bus inside the device.
Audio CDs can also be played.
The following are located on the navigation DVD:
Program data for the navigation computer
Voice segments for voice output
Map data.
A distinction is made between digitized and non-digitized areas within the DVD map area:
Villages, towns, roads, intersections and their attributes (e.g. one-way streets, no turns etc.) are recorded
in the digitized map area.
Included in the non-digitized areas are, for example company/private grounds, farms, small housing
estates, tracks across fields and areas between villages.
No data is available here.
Diagnosis interface (K-line) and fault management of D2B-components
During operation, the system stores all occurring faults in the nonvolatile memory. It is not possible to output
the fault via the display of the radio (A2).
The radio's (A2) fault management also includes the D2B-components connected. For this purpose, each D2B
component has its own DTC memory. The faults are transmitted from the corresponding components via the
D2B to the radio (A2) and can then be read out via the diagnosis interface
RADIO AND NAVIGATION MODULE, FUNCTION - GF82.61-P-4109-04GI
Processing button actuations
The control buttons and switches on the function keypad on the radio and navigation module (A2/56)are read
in via the I/O ports of the microcontroller and transferred to the central processor. Depending on the system
function the button actuations are processed in the central processor or relayed to the other system components
via the digital data bus ( D2B ) in form of a data telegram.
Graphic preparation and image output
The graphics subsystem handles the preparation and output of the operating displays. The operating displays are
output internally to the display by the graphic subsystem via the RGB output ( R =red, G =green, B =blue).
The RGB signal contains information and amplitudes of the three basic colors Red, G reen and Blue as well

Map data.
The digitized map area on the CD-ROM contains towns, cities, streets, intersections and their attributes (e.g.:
one-way streets, turn prohibitions, ...). It does not contain information about company and private ground,
farms, housing estates and agricultural roads.
Gyrosensor
The gyrosensor determines the direction change of the vehicle. It is installed in the navigation processor .
Calibration is not required.

covering under the 60% rear seat.
Wiring harnesses should lie as straight and as flat as possible in the recesses of the transmission tunnel
from the center console cutout to the rear incision. White adhesive tape mark (6) should remain at the rear
end of the center console bracket (2).
10. Slide tab of the floor covering at the rear incision under wiring harnesses.
11. Install rear air duct (7).
2 bolts at the rear air duct.
12. Route wiring harness for auxiliary interface module (8), wiring harnesses for video and DVD player (9)
