cancel beforehand, the navigation system
will still not be ready for operation.
After start-up or initial start-up, the navigation
system must perform a position finding
operation. As a result, you may have to drive
for some time until precise route guidance
takes place.
GPS Reception
The correct functioning of the navigation
system is also dependent on the GPS
reception. In certain situations, the GPS
reception may be impaired, distorted or even
impossible, e.g. in tunnels, multi-storey car
parks or due to snow on the GPS antenna. If
there is snow on the GPS antenna, you should
remove it. The GPS antenna is at the rear on
the vehicle's roof.
Route Guidance after Vehicles
Transport
After vehicle transport (e.g. by ferry, car train
or by towing) COMAND must determine the
vehicle location again.
Position finding takes place automatically
when the vehicle is driven off again, even if
COMAND is switched off. The actual length of
time may vary from case to case.
While the vehicle is determining its position,
route guidance is subject to the following
restrictions:
R Navigation announcements, route
guidance displays and displayed street
names do not match the actual location.
R COMAND does not issue any navigation
announcements.
R The message Off Mapped Road and a
direction arrow are displayed instead of the
route guidance displays. The arrow
indicates the direction of the destination.
i Direction arrow accuracy is also
dependent on correct vehicle position
and/or direction.
Once the position finding operation has been
completed, route guidance takes place again
via navigation announcements and route
guidance displays.
Interrupting Journey during Route
Guidance
i An interruption in the journey means
parking the vehicle and switching off
COMAND.
The continuation of the journey means
switching COMAND on again and
continuing to drive.
If interrupt the journey during route guidance
and continue it later, the following applies:
R If you continue the journey within 2 hours,
COMAND automatically continues route
guidance.
R If you continue the journey after 2 hours,
route guidance is cancelled. You will have
to continue the cancelled route guidance
again manually ( Y page 85).
Measurement Units
The measurement units displayed in
navigation mode are identical to those set in
the instrument cluster.
Input Restriction
There is an input restriction for vehicles for
certain countries.
The restriction is active for vehicle speeds
above approx. 3 mph. The restriction is
deactivated as soon as the speed falls below
approx. 2 mph.
Certain entries cannot be made when the
restriction is active, e.g. a city or road entry.
This is indicated by the fact that certain menu
items cannot be selected.

Route calculation takes some time. The
length of time depends on, e.g. distance to
the destination. COMAND calculates the
route using the digital map data. The
calculated route may deviate from the
actual road situation, e.g. as a result of road
works or incomplete map data. Please refer
to the information on the digital map
( Y page 58).

External Authorization
If COMAND cannot find your mobile phone,
this may be due to special security settings
on your mobile phone. In this case, you can
check whether, conversely, your mobile
phone can find COMAND.
