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.”
Updating map software: Proceed as
described in the “Updating the map
software” section (
page 149). 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 no reception at all, e.g. in
tunnels, in multistory parking garages or
there is snow covering the trunk lid where
the GPS antenna is located. If there is
snow on the trunk lid it should be removed.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.

Instead of the route guidance displays,
you see the “Off Road” display and a di-
rection arrow. The direction arrow
shows the compass heading to the des-
tination.
iPlease 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.

COMAND navigation (introduction)
When positioning is complete, route guid-
ance is once again possible using naviga-
tion announcements and route guidance
displays.
Interrupting the journey during route
guidance
The following applies if you interrupt the
journey during route guidance and contin-
ue the journey later:

COMAND resumes route guidance au-
tomatically if you continue the journey
within 2 hours.

Route guidance is canceled if you con-
tinue the journey after more than
2 hours. It will be necessary to resume
the canceled route guidance manually
(
page 203).Hard disk errors
COMAND has an integrated hard disk on
which the map software is saved.
If an area of the hard disk has an error,
COMAND can no longer access the map
data in this area, for example, when calcu-
lating a route.
The message “Navigation Unavailable.
Please refer to the operating instructions.”
appears.
Deleting message: Switch COMAND
off and back on.
Units of measurement
The units of measurement in navigation
mode are identical to those set in the in-
strument cluster.
Input restrictions
The input restrictions are imposed starting
at a particular vehicle speed. The restric-
tions are canceled as soon as the speed
drops below a certain value.
When the restriction is active, certain oper-
ations or entries are not possible.
You will notice this by the fact that some
menu items cannot be selected or certain
operations will not be possible.
iThe journey is interrupted if you park the ve-
hicle and switch off COMAND.
The journey is continued when you switch
COMAND back on and start driving on.
iIf you switch the navigation system off/on,
it will be operational again until it has to access
the faulty area of the hard disk again. The mes-
sage will then appear again. Consult an autho-
rized Mercedes-Benz Center.
