Navigational mode
What is navigation?
Navigation (Latin navigare = to travel by
sea) is generally understood to mean find-
ing the position of a vehicle, determining
the direction of and distance from the de-
sired destination, and establishing and fol-
lowing a route to this destination. Naviga-
tional aids include the stars, distinct
objects, a compass, and satellites.
The Traffic Assist uses its GPS receiver to
find the vehicle's position. (The Global
Positioning System (GPS) was developed
by the US military in the 1970s as a mis-
sile guidance system.
GPS is based on a total of 24 satellites cir-
cling the earth which continuously emit
signals. The GPS receiver receives these
signals and uses the delay of each of the
signals to calculate its distance from the
individual satellites. In turn, it can use this
information to determine its current geo-
graphical position.
The signals of at least three satellites are
needed to establish a position. If four or
more signals are available, the height
above sea level can also be calculated).
Traffic Assist determines the direction of
and distance to the destination with the
aid of a digital road atlas on the SD card
and the navigation computer.
For safety, directions to the designation
are
mainly provided verbally.
The direc-
tion display and map diagram on the
touchscreen are further aids.
WARNING
• Traffic regulations always take prece-
dence in all circumstances. The navi-
gational system is only an aid and
should not be substituted for the per-
sonal judgment of the driver. The di-
rections/details provided may in some
cases be incorrect. The driver must al-
ways decide whether or not to follow
the details given.
• Precedence should always be given to
actual traffic signs and local traffic
rules.
• The directions only relate to cars. Spe-
cial recommendations and rules for
other vehicles (e.g. utility vehicles)
and/or pedestrians are not taken into
consideration.
• Destinations may only be input when
the vehicle is stationary.
Note:
When first started up, it may take up to
30 minutes before a position can be
determined.
