General Information
Operational Readiness of the
Navigation System after the System
Software Update
Sometimes the installed map software is no
longer compatible following a system
software update by an authorized Mercedes-
Benz Center. In this case, the navigation
system is not operational.
X To update map software: Proceed as
described in the “Update Process” section
(Y page 49). Use map software compatible
with the system software.
i Please note that in this case the update
must run through right to the end. If you
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 Vehicle 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:
RNavigation announcements, route
guidance displays and displayed street
names do not match the actual location.
RCOMAND does not issue any navigation
announcements.
RThe 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 the
vehicle.
The continuation of the journey means
switching the vehicle on again and
continuing to drive.
