Control systems COMAND navigation (introduction) 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." Updating map software: Proceed as described in the "Updating the map software" section ( page 159). 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. The roof cargo container* may also impair mobile phone reception and GPS coverage. Route guidance after vehicle transportation COMAND has to redetermine the position of the vehicle if the vehicle has been transported (e.g. by ferry, by train or after towing). Positioning takes place automatically even when COMAND is switched off. The duration varies from one case to another. Route guidance may be restricted as follows during vehicle positioning: Navigation announcements, route guidance displays and displayed street names are not consistent with the actual location of the vehicle. COMAND does not generate navigation announcements. 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 Correct functioning of the navigation system depends on GPS reception, among other things. In certain situations, GPS reception may be impaired, there may be interference or there may be no reception at all, e.g. in tunnels, in multistory parking garage 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 back of the vehicle roof. 163

Control systems
COMAND navigation (introduction)
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 au-
thorized Mercedes-Benz Center, the in-
stalled map software may no longer be
compatible. If this is the case, the naviga-
tion 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 soft-
ware must be updated now. Please insert
the DVD with the map software.
²
Updating map software:
Proceed as
described in the “Updating the map
software” section (
³
page 159). Use
map software which is compatible with
the system software.
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
Correct functioning of the navigation sys-
tem depends on GPS reception, among
other things. In certain situations, GPS re-
ception may be impaired, there may be in-
terference or there may be no reception at
all, e.g. in tunnels, in multistory parking ga-
rage 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 back of the vehicle roof.
The roof cargo container* may also impair
mobile phone reception and GPS cover-
age.
Route guidance after vehicle transpor-
tation
COMAND has to redetermine the position
of the vehicle if the vehicle has been trans-
ported (e.g. by ferry, by train or after tow-
ing).
Positioning takes place automatically even
when COMAND is switched off. The dura-
tion varies from one case to another.
Route guidance may be restricted as fol-
lows during vehicle positioning:
°
Navigation announcements, route
guidance displays and displayed street
names are not consistent with the ac-
tual location of the vehicle.
°
COMAND does not generate navigation
announcements.
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-op-
erational.
