Introduction
The digital maps generated by the map soft-
ware become outdated in the same way as
conventional road maps. Optimal route guid-
ance can only be provided by the navigation
system in conjunction with the most up-to-
date map software.
Information about new versions of the digital map can be obtained from a Mercedes-Benz
Service Centre. You can have the digital mapupdated there with a DVD, or you can update
it yourself.
In some countries, it is possible to update the map data for COMAND Online free of charge
for a period of 3 years. Information on the
availability of this service for your vehicle can be obtained from your Mercedes-Benz Ser-
vice Centre. If the free update is not available
in your country, please read the "Updating
process" section.
Entitlement to the free update
For the first three years after your vehicle is
registered, you are entitled to all available
updates to the map software for
COMAND Online. They are usually installed
during a regular vehicle service. After this
period, you can purchase further updates
from your Mercedes-Benz Service Centre.
The free updates relate to the vehicle and not
to an individual. If there is a change of own-
ership within 3 years of first registration, the
new owner is entitled to the map software
updates.
Availability of free updates
Enter your e-mail address at http://
www.mercedes-benz-accessories.com/
comand-infomail. You will receive a one-off e- mail containing information on how to updatethe map software. Please also visit http://
www.mercedes-benz-accessories.com/
navigation-updates to find out if map soft- ware updates for your vehicle are available at
your Mercedes-Benz partner.
Updating at the Mercedes-Benz Service
Centre
If an update for your map software is availa-
ble, you will receive it free of charge at your
Mercedes-Benz Service Centre during your
vehicle's annual service. You can arrange a
separate appointment for this at your
Mercedes-Benz Service Centre on request.
The update is performed only by a Mercedes- Benz Service Centre for European map data.
The map software is not provided on a data
medium.
Carrying out the update yourself
i The update process may take some time
(over an hour), depending on the size of the
digital map. During this time, you will only
be able to switch on radio mode and to
accept incoming calls. The update will be
completed more quickly if the vehicle is
stationary.
If you start the update with the engine
switched off and the starter battery has
insufficient power, COMAND Online may
automatically switch off. This preserves the battery. If this occurs, restart the update
with the engine running.
X Insert the DVD:
R in the single DVD drive (Y page 469)
R in the DVD changer (Y page 469)
COMAND Online checks whether the digi-
tal map on the DVD is compatible with the
navigation system and system software.
A prompt then appears asking if you want
to install the database. Versions of the
database currently installed and the data-
base that is to be installed are displayed.
X Select Yes
Yes orNo No and press Wto confirm.
After selecting Yes
Yes, an activation code
must be entered when installing a database
for the first time. You will receive the acti-
vation code when you buy the navigation
DVD. Navigation

R Bluetooth ®
device name
Every Bluetooth ®
device has a Bluetooth ®
device name. This device name is freely
definable, but can be identical for all devi-
ces from the same manufacturer. It is
therefore recommended that you change
this name so that you can easily recognise
your mobile phone (see the mobile phone

market are equally suitable. Further infor-
mation on suitable mobile phones and
