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 Navigation device, 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 Navigation device 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.

• Traffic guidance is restricted to

passenger vehicles. Special driving

recommendations and regulations

for other vehicles (e.g. commercial

vehicles) are not included.

• Destinations may only be entered

when the vehicle is stationary.
