Navigation mode
What is navigation?
The term "navigation" (lat. navigare = to
travel by sea) is generally understood to
mean the location of a vehicle, the determination
of the direction and distance
from the desired destination and the determination
of the required route. Stars,
prominent landmarks, compass and satellites
etc. are used as navigation aids.
With the Traffic Assist Pro, 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 orbiting
the Earth and emitting signals. A
GPS receiver receives these signals and
uses the signal times to calculate the distance
to an individual satellite, 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 Traffic Assist Pro 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 only
an aid. Errors may occur in individual
data items/entries. At all times, the
driver must decide whether or not to
heed the information provided.
We do not accept liability for erroneous
data 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.
