General notes
Operational
readiness
of the navigation
system following a system software
update by an authorized Mercedes-
Benz Center
After a system software update by an
authorized Mercedes-Benz Center, the
installed map software may no longer be
compatible.
If
this is the case, the navigation
system will not be operational.
You will know if this is the case, when the
following message will appear when you
switch to navigation mode: The system
software has been updated. The map
software must be updated now. Please
insert the DVD with the map software.
X
Updating map software: Proceed as
described in the “Updating the map
software” section (Y page 83). Use map
software which is compatible with the
system software.
i
Please note that the update must be
allowed to
run to the end in this case. If you
interrupt it, the navigation system will
continue to be non-operational.
Initial use or use following a system
software update
In both these cases, the navigation system
must determine the position of the vehicle.
You may have to drive for a while before
precise route guidance is possible.
GPS reception
The Navigation system relies on a number of
factors to function correctly. GPS reception
is very important.
In
certain
situations GPS may be impaired, for
example:
R
in tunnels
R
in parking garages
R
due to snow on the GPS antenna
If there is snow on the trunk lid where the GPS
antenna is located, you should remove it.
Route guidance after transporting the
vehicle or exiting a parking garage
COMAND has to redetermine the position of
the vehicle
if the vehicle has been transported
(e.g. by ferry, by train or after towing).
COMAND may also have to redetermine the
vehicle position when leaving a parking
garage.
The proper position of the vehicle will even be
found if you are driving with COMAND
switched off. The duration of the positioning
recalculation will vary case by case.
During positioning, route guidance may be
inaccurate and may show the following:
R
Navigation announcements, route
guidance displays and displayed street
names are not consistent with the actual
location of the vehicle.
R
COMAND does not generate navigation
announcements.
R
Instead of the route guidance displays, you
see the Off Road display and a direction
arrow. The direction arrow shows the
compass heading to the destination.
After the vehicle position has been
redetermined, route guidance with navigation
announcements and route guidance display
is available again.
