Prerequisites for the mobile phone
For making calls using COMAND via the
Bluetooth
® interface, you will need a Blue-
tooth-enabled mobile phone.
i Not all mobile phones available on the mar-
ket are comparably suitable. Further information
on suitable mobile phones and connecting Blue-
tooth-enabled mobile phones to COMAND is
available via the Internet at www.mbusa.com.
Activating Bluetooth®
Before you begin activation of your mobile
phone connection via the Bluetooth® inter-
face please ensure it is compatible with
Bluetooth
® handsfree profile 1.0
(
mobile phone operating guide)
Switch on the mobile phone and enter
the PIN, if applicable (
mobile phone
operating guide).
Activate Bluetooth® connection on the
mobile phone (
mobile phone operat-
ing guide).
i On certain mobile phones, not only do you
have to activate the Bluetooth® function but the
device must also be made “visible” for other de-
vices.
Each Bluetooth
® device has a Bluetooth® device
name. It is recommended to give the device a
personal name, by which you can clearly recog-
nize your mobile phone.
i If the Bluetooth function on the
COMAND is switched off, the message “Blue-
tooth not activated in system settings.” appears.
Activate Bluetooth® connection on
COMAND (
page 169).
Registering a mobile phone
(authorizing)
When you use your mobile phone in con-
junction with COMAND for the first time,
you must register (authorize) it.
It is possible to register several mobile
phones. The connection is always estab-
lished to the mobile phone that was acti-
vated last. When you authorize a new
mobile phone, it is activated automatically.
You can switch between the authorized
mobile phones (
page 88).Searching for a mobile phone
In the phone submenu select “Phone”
K “Phone List” K “Update”.
COMAND searches for suitable Blue-
tooth
® phones within range and enters
them in the phone list.
i The duration of the search procedure de-
pends on the number and type of Bluetooth®
phones. The search may take a few minutes.
When first entering the device list and be-
fore running an update, the black
dotRindicates the active phone (found
and authorized).
After running an update:
Phone icons 3 indicate if a phone is found
(black) or not (grey).

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.

(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.
