Navigation OverviewHow 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. Thanks to the detailed informatio n on the navigation CD
the measurements values are compared and if necessa ry they are updated
using the traffic reports ( TMC = Traffic Message Channel). An optimal route to
the destination is determined in this way.

SafetyThe navigation system determines the position of the vehicle, the direction
and distance and the route to a selected destination w ithout taking traffic
regulations into account. Navigation recommendations are given as
announcements by the system. Direction arrows are al so shown on the
screen. The destination is entered when the vehicle is stationary. The desti-
nation guide function is designed for cars and is thus unsuit able for larger
commercial vehicles.

The last audio instruction can be r epeated by pushing the button. The
volume of a navigation recommendation can be changed whilst it is being
made.
If the display Off Road appears on the screen, it means you are on a rout e not
recorded on the CD, e.g. on a dirt road. The GPS satellites will not be able to
reach your antenna when you are in a tunnel or undergrou nd 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 an ann ouncement indi-
cating that you are located on a street fo r which no digital record exists. Drive
on until the display Off Road disappears.
