14Navigation OverviewHow does the navigation system work, and how is it operated?
An optimal route is defined using sensors, satellites and
traffic reports and the driver is then guided to his or her
destination.The current vehicle position is determined using a system of satellites
(GPS - Global Positioning System). Sensors in the vehicle measure
distances that have been driven. Measured values are compared using
the detailed map material on the navigation CD and corrected with the
assistance of TMC traffic announcements as necessary. An optimal route
to the destination is determined in this way.
Navigation announcements and direction arrows shown on the screen
and in the combi-instrument guide you safely and conveniently to your
destination. You can drive to a given address in towns you are unfamiliar
with, or drive to the nearest garage or be guided to a hotel.

SafetyThe navigation system determines the position of the vehicle, the direction
and distance and the route to a selected destination without taking traffic
regulations into account. Navigation recommendations are given as
announcements by the system. Direction arrows are also shown on the
screen. The destination is entered when the vehicle is stationary. The
route guidance function is designed for cars and is thus unsuitable for
larger commercial vehicles.

try to carry out a route calculation in this situation you may hear the
announcement: “You are located on a non-digitalised street”. Drive on until

entry” – Field for entering a stopover destination. A stopover destina-
tion is entered in the same way as a destination. A stopover destination is
deleted from the screen as soon as it has been reached. It will, however,
remain in the memory Last dest.Ÿpage 17, “Destination entry”. If the
stopover destination is reached, you will be informed that you have
reached your destination, and route guidance to the final destination is
started automatically. If the stopover destination is not reached exactly,
e.g. because it is not located directly on a road, you will be informed that
you have reached the destination area. Route guidance to the next desti-
nation is not started automatically.

Position display
The current information on the position of the vehicle is
shown here.
GPS status (number of satellite receptions, positioning mode)
including the direction and distance to destination (with active route
guidance).
Direction of travel
Altitude (GPS altitude). If too few satellites are received to calculate
the altitude, the display is green.
v
GPS position (longitude)

GPS position (latitude)
The direction of travel is shown in degrees and also in the form of a
compass.
The GPS status shows the number of satellites as dots and also shows
the positioning mode (NO FIX, 2D FIX, 3D FIX).
x
NO FIX – The GPS reception is not sufficient to fix the position of the
vehicle.
x
If the position definition for NO FIX is only possible using the wheel
sensors (underground garage etc), the GPS coordinates will be displayed
in green. The GPS coordinates will no longer be shown following a long
distance with NO FIX in the display or if it is not possible to determine the
position.
x
2D FIX – The horizontal position of the vehicle can be determined, but
not the altitude (altitude display is green).
x
3D FIX – Position and altitude can be determined.
The altitude given is accurate to r15 m at altitudes between 0 m and
+5000m. The system will be less accurate if the GPS reception is bad or
weather conditions are poor.
The direction to the destination is shown in the form of a marking outside
the compass. If the destination is not in the area displayed by the compass
(i.e. to the side or behind the vehicle), the marking is shown as an arrow
to the side in question.
