General information
9 Warning
The navigation system is an aid to
your navigational abilities and
does not replace them. Drive with
due care and attention and adopt
a safe, vigilant attitude.
If a navigation system instruction
contradicts traffic regulations, the
traffic regulations always apply.
The Navigation system will reliably
guide you to your chosen destination
without the need for physical road
maps.
If the Traffic info service is available
in your country or region, the current
traffic situation is also considered in
route calculations. The system
receives traffic messages in the
current reception area.
To receive the most up-to-date, real-
time traffic information possible,
subscribe to the Live services facility
via the TomTom™ website.
Functioning of the Navigation
system
The position and movement of the
vehicle are detected by the
Navigation system using sensors.
The distance travelled is determined
by the vehicle's speedometer signal,
and turning movements on bends are
determined by a gyro sensor. The
position is determined by GPS
(Global Positioning System)
satellites.
By comparing these sensor signals
with the digital maps on the
Navigation system SD card, it is
possible to accurately determine the
position of the vehicle.
When using the vehicle for the first
time, or after a ferry trip, etc., the
system will self-calibrate. It is,
therefore, normal if it does not provide
an exact location until the vehicle has
travelled for some distance.
After the entry of the destination
address or point of interest (nearest
petrol station, hotel, etc.) the route is
calculated from the current location to
the selected destination.
