Navigation Mode What is navigation?
The term "navigation" (lat. navigare = to
travel by sea) is generally understood to
mean the determination of a vehicle’s
location, the determination of its
direction and its distance from the
desired destination and the required
route to get there. Stars, prominent
landmarks, compasses and satellites
etc. are used as navigation tools.
With the Navigationsgerät, the location is
determined by the GPS receiver. The
Global Positioning System (GPS) was
developed during the 1970s by the US
military as a weapons guiding system.
GPS is based on a total of 24 satellites
which orbit the Earth and transmit
signals. A GPS receiver receives these
signals and calculates its distance to the
individual satellites based on the signal
travel times, and then determines your
current geographical position.
Signals from at least three satellites are
required to determine your position;
your height above sea level can be
calculated if signals are received from
four or more satellites.
The Navigationsgerät determines the
direction and distance from the
destination using a navigation computer
and a digital street map held in its
internal memory.
For safety reasons, route guidance is
given predominantly in spoken form.
This is supported by a direction indicator
and a map display on the touch screen.
¤ Safety instructions
• Road traffic regulations always take
priority. The navigation system is
merely an aid, data/information may
in select cases be incorrect. The driver
must decide in each situation by him-
or herself if he or she will follow the
directions.
No liability will be assumed for
incorrect directions provided by the
navigation system.
• When first put into use it can take up
to 30 minutes to fix the position.
• Observation of traffic signs and local
traffic regulations must always take
priority.
• The traffic routing is only related to
passenger cars and motorcycles.
Special driving recommendations and
regulations for other vehicles (e.g.
commercial vehicles) are not taken
into account.
• Destinations may only be entered
when the vehicle is stationary.
