Control systems
COMAND navigation (introduction)
ț 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.
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:
ț COMAND resumes route guidance au-
tomatically if you continue the journey
within 2 hours.
ț 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 214).
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.
i
The 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.
i
If 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.
