COMAND navigation (introduction)
Map software
The digital maps generated by the map
software become outdated in the same
way as conventional road maps. Optimum
route guidance can only be provided by the
navigation system in conjunction with the
most up-to-date map software.
Information about new map software ver-
sions can be obtained from an authorized
Mercedes-Benz Center.
Updating the map software
You can update the map software yourself
using a DVD.
Notes about handling DVDs

Only hold discs by the edge.

Handle discs carefully to prevent read
problems.

Avoid getting scratches, fingerprints
and dust on discs.

Use a commercially-available cleaning
cloth to clean discs. Do not wipe them
with a circular motion, but only in
straight lines from the center out-
wards.

Place discs back in their boxes after
use.

Protect discs from heat and direct sun-
light.
Updating process
The updating process has the following
phases:

Loading a DVD into the DVD changer
(
page 160)

Updating process (page 160)
iThe updating process can take between
10 and 60 minutes, depending on the size of the
map software. If the radio was switched on be-
fore you started the updating process, you can
still adjust the volume. You can also use
COMAND to operate the automatic air condition-
ing and to cancel the process. Other functions
are not operational.
If possible, carry out the update when the vehicle
is stationary.
iIf you carry out the update with the engine
switched off and the vehicle battery has insuffi-
cient power, COMAND may automatically switch
off during the process in order to protect the bat-
tery. If this occurs, restart the update with the
engine running period. Similarly, if the SmartKey
position is unintentionally switched to 0, restart
the update.
Warning!G
Never leave the engine running in an en-
closed space. The exhaust gases contain
carbon monoxide. Inhaling exhaust gases
constitutes a health hazard and could lead
to loss of consciousness or even death.
