4. Using Navigation
What is navigation?
The term "navigation" (lat. navigare = to travel by
sea) is generally understood to mean the determina-
tion of a vehicle’s location, the determination of its di-
rection and its distance from the desired destination
and the required route. Stars, prominent landmarks,
compasses and satellites etc. are used as navigation
tools.
TrafficPro uses a comparison of its sensor system
with the data of a digital map and the help of the GPS
(Global Positioning System) receiver to determine lo-
cation. It determines the direction and distance from
the destination by means of a digital street map, a nav-
igation computer and sensors. A speedometer and re-
verse signal are also used to calculate the route.
For safety reasons, route guidance is provided pre-
dominantly in spoken form , supported by a direction
indicator on the display.
Safety Instructions
- All traffic rules must be observed at all times.
- Observation of traffic signs and local traffic regu-
lations must always take precedence over instruc-
tions given by TrafficPro.
- 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.
Navigation CD
Your TrafficPro is shipped with two navigation CDs.
One CD contains data for the western half of the USA
and the other contains data for the eastern half of the
USA.
Data for North Dakota, South Dakota, Nebraska,
Kansas, Oklahoma, and Texas are contained on both
CDs (the striped area on the illustration).
The navigation CDs contain a digitized street map.
Highways, state and county roads, as well as local
streets are detailed in this street map. Larger cities and
communities are mapped in detail. For smaller towns
and communities, the regional and unclassified roads
or through-roads and the town centers are included.
One-way streets, pedestrian zones, no-turn intersec-
tions and other traffic regulations are taken into ac-
count as much as possible. There may be discrepan-
cies between the data on the navigation CD and the
actual local situation, due to continuous changes to
road systems and traffic regulations.
