Navigation operation

What is navigation?

N a v i g a t i o n o p e r a t i o n
The term "navigation" (lat. navigare = to travel by sea) is gen-
erally understood to mean the location of a vehicle, the deter-
mination of the direction and distance from the desired
destination and the required route. Stars, prominent land-
marks, compasses and satellites etc. are used as navigation
tools.
With this unit, the location is determined via the GPS receiver
(GPS = Global Positioning System). The direction and dis-
tance from the destination is determined using a digital street
map, a navigation computer and sensors. A speedometer and
reverse signal are additionally used to calculate the route.
For safety reasons, route guidance follows predominantly in
spoken form supported by a direction indicator on the dis-
play.

Safety instructions

• The requirements of the Road Traffic Regulations (RTR)
apply.
• Observation of traffic signs and local traffic regulations
always takes priority.
• Traffic guidance is restricted to passenger vehicles. Spe-
cial driving recommendations and regulations for other
vehicles (e.g. commercial vehicles) are not taken into ac-
count.
• The destination must only be entered when the vehicle is
stationary.

Digitised area

The navigation CD provided contains a digitised street map.
Motorways, federal and regional roads, as well as district
roads are detailed in this street map. Larger cities and bor-
oughs are completely covered. The regional and unclassified
roads or access roads and the town centre for smaller towns
and boroughs are included.
One way streets, pedestrian zones, turn bans and other traffic
regulations are taken into account as far as possible. There
may be discrepancies between the data on the navigation CD
and the actual local situation, due to permanent changes to
road systems and their traffic regulations.
