Overview
How

the n

i
on
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 position
is
det
ermin
ed using
a
sate
llite 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 traffic reports
(TMC
=
Traffic Message Channel)

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
re
c
ommendations
or
leave the
recommended
route. This process takes only a few
seconds
.
Navigation

only
be
made

is
complete.

and
traffic
conditions
are
such
that
it is safe to
