Overview
How does the navigation system work and how
is
it operated?
An optimal
route
is defined using sensors, satellites and traffic reports and
the
driver is then guided to his or her
destination.
The current vehicle
posit
ion is determined
using
a
satellite system
(GPS -
Global Positioning
System). Sensors in the vehicle measure
dis-
tances that have been driven.
The values are
compared to the
detailed map
information on a
navigation DVD
and
are corrected as
necessary
with
the
support
ofTMC

reports

The
system
provides
navigation
recommendations in the
form
of spoken naviga-
tion
announcements. Direction arrows
indi-
cating the
direction
of
travel
are also
displayed
on the
screen.
The
destination is entered when
the
vehicle is
stationary. The route guidance
function is
de-
signed for cars and
is
therefore unsuitable for
larger
commercial
vehicles.
The route is recalculated each time
you
ignore
recommendations
or leave
the recommended
route.
This
process
takes only a few
seconds.
Navigation recommendations
can
only
be made
again when the process
is complete.
Depending
on the country. some
radio naviga-
tion system
functions
can
no longer
be
selected
when the vehicle
is
travelling
above a certain
speed.
This
is not
a
malfunction, but
simply

legal
requirements
valid in
this country.

WARNING
Please keep your attention on driving at all
times. Accidents and injuries
can
occur if the
driver is distracted.
•
Do not allowyourselfto be distracted from
the road by making settings or by using the
radio/navigation
system.
•

when
the road, weather and traffic
conditions are
such that it is
safe
to do
so.
• The
volume

e.g. police or fire brigade sirens, can be heard
at all times.
&.
WARNING
Please observe the laws of road traffic
legisla-
tion when folloMng the recommendations
made by your radio/navigation
system.
• The recommendations made by the
system
can differ from the
actual
road
situation,
e.g.
due to road works or outdated navigation
data. In these cases, traffic legislations should
always be followed
and
recommendations
made by the navigation system ignored.
• Traffic
signs
and legislations always take
priority over the recommendations made by
the navigation
system.
•
Even if information

still
subject
to constant changes. Information regarding
traffic lights. stop

and right of way
signs,
parking
and
stopping restrictions, as well as
