Activating the mobile phone
The check marks 1 indicate if a phone
has been authorized (black) or not (grey).
If a phone is not in the vehicle but has been
authorized previously, the phone symbol
and the check mark are grey 2.
i If the device list already contains ten autho-
rized devices, you must de-authorize one of the
authorized devices (
page 88). You will then
have to switch this device off and start the
search again. Otherwise the new device you are
looking for will not appear in the list.
To start search again:
Select “Update”.
Entering passcode
Select the as yet unauthorized device
(no check mark yet) from the list.
Select “Options” K “Authorize” or
Press n.
The input menu for the passcode ap-
pears.
i The passcode is any number chosen by you
between one and sixteen digits in length. We rec-
ommend to use at least four digits because this
improves the quality of the encryption during
connection. The passcode can differ during each
authorization for each device. You must enter
the same number on COMAND and on the device
to be authorized. Please also refer to the instruc-
tions in the mobile phone operating guide.
To enter from COMAND: Select the
digits in the menu bar one after the oth-
er.
To correct entry: Select õ.
To cancel entry: Select “Back”.
To confirm entry: Select B.If a Bluetooth
® connection is established
successfully, you will be prompted to enter
a code on the mobile phone (
mobile
phone operating guide).
Enter the same passcode on the mobile
phone as you did on COMAND.
The device is authorized. You can now
make calls via COMAND’s hands-free
device using the authorized
mobile phone.
External authorization
If COMAND cannot find your mobile phone,
this may be due to special security settings
on your mobile phone. In this case, you can
check whether, conversely, your mobile
phone can find COMAND.

Introduction
An unsuccessful update may be caused by
one of the following:

DVD dirty or scratched.
Clean the DVD.
Please refer to the “Notes on DVD
discs” section (
page 112).
Restart the update.

Overheating as a result of excessively
high temperatures in the passenger
compartment.
Wait until the passenger compart-
ment has cooled down.
Restart the update.

The memory medium (hard drive) inte-
grated into COMAND has a physical de-
fect.
Contact an authorized
Mercedes-Benz Center.Operational readiness of the navigation
system after the system software up-
date
Sometimes the installed map software is
no longer compatible following a system
software update by an authorized
Mercedes-Benz Center. In this case, the
navigation system is not operational.
To update map software: Proceed as
described in the “Update process” sec-
tion (
page 114). Use map software
compatible with the system software.
i Please note that in this case the update
must run through right to the end. If you cancel
beforehand, the navigation system will still not
be ready for operation.
After start-up or initial start-up, the naviga-
tion system must perform a position find-
ing operation. As a result, you may have to
drive for some time until precise route
guidance takes place.
GPS reception
The correct functioning of the navigation
system is also dependent on the GPS re-
ception. In certain situations, the GPS re-
ception may be impaired, distorted or even
impossible, e. g. in tunnels, multi-storey
car parks or due to snow on the GPS anten-
na. If there is snow on the GPS antenna,
you should remove it. The GPS antenna is
at the rear on the vehicle’s roof.
Route guidance after vehicle transport
After vehicle transport (e. g. by ferry, car
train or by towing) COMAND must deter-
mine the vehicle location again.
Position finding takes place automatically
when the vehicle is driven off again, even if
COMAND is switched off. The actual length
of time may vary from case to case.
While the vehicle is determining its posi-
tion, route guidance is subject to the fol-
lowing restrictions:

Navigation announcements, route
guidance displays and displayed street
names do not match the actual loca-
tion.

Route guidance begins after the route
has been calculated (
page 148).
i Route calculation takes some time. The
length of time depends on, e. g. distance to the
destination. COMAND calculates the route using
the digital map data. The calculated route may
deviate from the actual road situation, e. g. as a
result of road works or incomplete map data.
Please refer to the information on the digital map
(
page 112).
If necessary switch to navigation mode
and display menu system

page 118).
Select “Destination” K “From Memo-
ry”.

played without predictive speller
(
page 137).
i There is always an entry in the destination
memory with the name “My Address”. You can

entry and select it for route guidance
(
