Information about GPS
Information about GPS
The GPS (Global Positioning System) allows
worldwide navigation and locating via satellites to
determine a position.
GPS mode of operation
The navigation device measures the current posi-
tion of your vehicle via GPS and compares these
coordinates with its map material. The map mate-
rial contains the geographic coordinates of points
of interest, streets and cities that you can view on
the display of the navigation device. The device
uses this information to calculate the route to the
destination you entered.

of the navigation device. For this purpose,
please read the chapter "Route guidance",
"Disturbed GPS reception".
