Basic features
The balance and fader settings apply for all signal sources (radio, CD, voice output).
The base and treble settings can be stored separately for the following signal sources:
Radio
Traffic announcements
Navigation voice output
Integrated CD player
Optional CD changer
Volume and tone settings for traffic announcements
The volume for traffic announcements can be changed during a traffic announcement (procedure analog to
adjusting navigation system voice output).
Volume and tone settings for navigation system voice output
The volume is automatically increased by a defined level during voice output. The volume level increase can be
set in stages directly at the radio (A2). The radio is preset to 6 dB.
During voice output, the volume can be changed with the left knob. The base/treble settings can be changed
with the right knob after pressing the "tone" button (during voice output). The settings can be continued after
conclusion of the voice output; the setting mode is terminated 8s after actuating the last button.

Navigation system - additional unit with CODE (818b) Single CD player - additional unit with CODE
(491) U.S. version
It is necessary to distinguish between audio and service sources on the radio and navigation module (A2/56) :
Audio sources are:
Radio
CD player
CC player
CD changer (code 819a)
Service sources include:
Voice output on navigation
telephone
Signal editing required for volume and tone settings is accomplished by the audio component integrated into
the radio and navigation module (A2/56)
If the vehicle is additionally equipped with a sound system (code 810), the sound amplifier (A2/13) ensures
final audio signal amplification.
Volume setting
By turning the volume knob the volume of the corresponding mode changes.
Tone setting
The tone settings as well as the general brightness adjustment of the display can be reached by pressing
the multifunction key" ADJ ". If the multifunction key" ADJ " is pressed for longer than 2 s all tone
settings of all modes jump back to the center position. This is confirmed by a short peep tone. The
adjustment possibilities for treble/bass, balance and fader are summarized in one display.
They can be selected by actuating the multifunction keys " " and " ". The corresponding setting can be
changed by actuating the multifunction keys"- " and "+ " or "L ", "R ", "F " and "R ".
These settings can also be made with the "joystick " in an analogous manner. When the headlamps are
switched on the brightness setting of the display can be reached by pressing the multifunction key" BRT" in the
tone setting menu. Here it is possible to select between " bright " and "dark ". Simultaneously pressing the
multifunction keys " - " and "+ " or "L " and "R " or "F " and "R " resets the corresponding setting in the
current mode to the center position
Tone setting is not possible in the telephone or navigation mode. The tone or brightness setting can be exited
by pressing the multifunction key EXIT ".

BASIC LOCATION FINDING, FUNCTION - GF82.61-P-3006GI

Fig. 47: Identifying Basic Location Finding, Function

Basic location finding (dead reckoning)
Is the basic function of permanent location finding It is accomplished permanently by the navigation processor
when the ignition is switched on and is not dependent on the CD-ROM map.
The current position is stored after the ignition is switched off.
The following information is calculated with the aid of basic location finding :
Distance traveled
Direction of motion (forward or backward) and
Direction in which vehicle is pointing
Basic location finding is accomplished approx. once per second .
Distance traveled
The navigation processor receives the signals output by the front right wheel speed sensor (L6/2) from the
traction system control module (N47) via discrete leads.
Evaluation of the wheel speed signals allows calculation of the distance traveled.
Direction of motion

In addition, the vehicle's course of travel is determined with the aid of the sequence of the locations calculated
with GPS.
Possible interference when receiving GPS signals
Since GPS operates in the GHz range (microwaves) and the signals are weak, reception interference can occur
as the result of:
atmospheric interference, e.g. weather, water vapor, fog
multiple reception resulting from reflecting of signals, e.g. from building walls
Signal shadows, e.g., in built-up areas, tunnel, in the proximity of higher buildings and trees
GPS reception therefore necessitates a clear view of the sky. The location finding accuracy of the GPS system is
100 m or better.

If the destination is in the near vicinity, a map area is loaded within a radius of approx. 100 km of the
vehicle location ("Local area").
For destinations further away, an area is selected surrounding the vehicle location, the destination and the
concrete route to the destination ("Corridor formation").
After storing the map data, the DVD with the map data can be taken out of the drive. Now, audio CDs can also
be played.
If the driver deviates too far from the calculated route during the course of navigation system and thereby leaves
the map area stored in the navigation processor, it may be necessary to insert the DVD again in order to
calculate a new route. The navigation processor requests this automatically.
Location errors
The errors are classified into 2 categories:
Incorrect position indication between 2 driving instructions (may not occur more than once every 500
km)
Incorrect driving instruction (may not occur more than once every 1,000 km)

General
Map-supported location finding is available only in the digitized area of the CD-ROM map.
By comparing the calculated vehicle position with the CD-ROM map it is possible to recognize and
automatically correct the deviation.
Function
The vehicle position is permanently followed by the navigation processor on the CD-ROM map. If the route
deviates from the calculated route the position coordinates of the basic location finding are corrected if
necessar
y.

FERRY
TOLL
After calculation of the route, the navigation processor makes up a list of the streets along the route. This route
list is used for navigation. It can be displayed during navigation by pressing the "I" (INFO) and "RTE" (Route)
buttons.
Route updating
If the driver deviates from the calculated route, a new route list is automatically calculated by the navigation
processor. The current position and the direction of travel are taken into consideration, and the new route is
optimized accordingly. This is accomplished without any message on the display.
Circumventing traffic jams with "Traffic jam" menu key function
After a traffic jam is reported on traffic radio and before reaching the affected section, a route can be calculated
for driving around the traffic jam. For this purpose, activate the "Traffic jam" menu and enter the length of the
traffic jam including the distance to the start of the traffic jam.
The "Traffic jam" function is also available for Federal and State highways as well as for inner city areas.
Trips outside the digitized map area
If the vehicle leaves the digitized DVD map area (e.g. driving into a multi-level car park), then no route can be
calculated or updated. "OFF ROAD" appears on the display. Upon leaving the map boundary, the display "OFF
MAP" appears.
Destinations which lie outside of the digitalized map area cannot be taken into consideration on calculation of
the route.

Navigation is the generation and output of driving recommendations, in order to guide the driver to the desired
destination. The prerequisites of destination guidance include:
Constant map matching is in operation (occurs automatically),
Destination was entered
Route has been calculated.
The navigation processor continuously compares the route calculation data with the ongoing location finding
data and derives from this measures for further navigation.
The navigation processor is integrated in the radio (A2).
Depending on the vehicle position, a distinction is made between the following navigation modes:
Destination within digitized DVD map area
Restricted navigation outside the digitalized DVD map area
