What is navigation?
The term “navigation” (lat. navigare = to
travel by sea) is generally understood to
mean the location of a vehicle, the deter-
mination of the direction and distance
from the desired destination and the
required route. As navigation aids, stars,
prominent landmarks, compass and sat-
ellites are used.
With Cascade, location is determined
with the GPS receiver (GPS = Global
Positioning System). The direction and
distance from the destination are deter-
mined using a digital road map, a navi-
gation computer and sensors. A speed-
ometer signal and a reverse signal are
additionally used to calculate the route.
For safety reasons, navigation is pre-
dominantly in spoken form supported
by a direction indicator on the display.
Navigation data
The Cascade is supplied with a CF mem-
ory card. This memory card contains
a digitised road map.
Motorways, federal and regional roads, as
well as district roads are stored in the dig-
itised street map. Larger cities and com-
munities are comprehensively covered.
For smaller towns and communities, the
regional and unclassified roads or access
roads and the town centres 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 memory card and the actual lo-
cal situation, due to permanent changes to
road systems and their traffic regulations.
