NavigationGeneral frameHow does the navigation system work, and how is it operated?
An optimal route is defined us ing sensors, satellites and
traffic reports and the driver is then guided to his or her desti-
nation.The current vehicle position is determined using a sy stem of satellites (GPS -
Global Positioning System). Sensors in the vehicle mea sure distances that
have been driven. Measured values are compar ed using the detailed map
material on the navigation CD and corrected with the assistance of TMC traffic
announcements as necessary. An optima l route to the destination is deter-
mined in this way.
Navigation announcements and direction arrows shown on the screen and in
the combi-instrument* guide you safely and conv eniently to your destination.
You can drive to a given address in towns you are un familiar with, or drive to
the nearest garage or be guided to a hotel.

A variety of different information on th e route can be called up during active
route guidance. The scroll function can be used to page th rough lists shown
on the screen, either line by line or page by page.
If the display “ Off Road
” appears on the screen, it means you are locate d on
a non-digitalised street, (e.g. on a fa rm track). The GPS satellites will not be
able to reach your antenna when you are in a tunnel or underground garage,
meaning that the unit orientates itself via the wheel sensors. If you 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 the display “Off
Road ” disappears.Main menu - Navigation– Press to display the main Menu of the navigation sy stem

Function keys in the Navigation main menu
– Starts route guidance to the entered destinatio n. Pressing this
button again will stop the route guidance function ⇒ page 38, “Route guid-
ance”.
– Field for entering your destination ⇒
page 18, “Destination
entry”.
–Allows entering a previous destination to the fina l
destination. A stopover destination is entered in the sa me way as a destina-
tion. Upon reaching the stopover, this disappears fr om the display, but stays
in the memory of the Last destinations
⇒ page 18, “Destination entry”.If the
stopover destination is reached, (you will be informed that “you have reached
your destination”), and route guidance to the fina l destination is started
automatically. If the stopover destin ation 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 del destino” area. Route guidance to the next
destination is not started automatically.

Position display
The current information on the position of the vehicle is
shown here.
GPS status (number of satellite re ceptions, positioning mode) including
the direction and distance to destin ation (with active route guidance).
Direction of travel
Altitude (GPS altitude). If too few satellites are re ceived to calculate the
altitude, the display is grey.

GPS position (longitude)

GPS position (latitude)
The direction of travel is shown in degr ees and also in the form of a compass.
The GPS status shows the number of satellites as dots and a lso shows the
positioning mode (NO FIX, 2D FIX, 3D FIX).
•
NO FIX – The GPS reception is not sufficient to fix the position of t he
vehicle.
•
If the position definition for NO FIX is only possible using the wheel
sensors (underground garage etc), the GPS coordi nates will be displayed in
grey. The GPS coordinates will no longer be shown followin g a long distance
with NO FIX in the display or if it is not possible to determine the pos ition.
•
2D FIX
– The horizontal position of the vehicle can be determined, b ut not
the altitude (is indicated in grey).
•
3D FIX – Position and altitude can be determined.
The altitude may oscillate between 0 m and +5000 m with a margin of error of
± 15 m. The exactness varies in function of the GPS recepti on quality or of the
climatic conditions.
The direction to the destination is shown in the form of a m arking outside the
compass. If the destination is not in the area displayed b y the compass (i.e.
to the side or behind the vehicle), the marking is sh own as an arrow to the
side in question.
