Introduction
52
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 .
Hard Disk Drive
COMAND has an integrated hard drive on
which the map software is stored.
If an area of the hard drive has a fault,
COMAND can no longer access the map data
in that area for the route calculation, for
example.
The message Navigation Unavailable will
then be displayed.
X To delete message: Switch COMAND off
and back on again.
i After switching on/off, the navigation
system will remain functional until it has to
access the faulty area of the hard drive
again. The message will be displayed again.
Contact a Mercedes-Benz service center.
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 apprx. 3 mph. The restriction is
deactivated as soon as the speed falls below
apprx. 2 mph.
Certain entries cannot be made when the
restriction is active, e.g. a city or road entry.

items cannot be selected.
