Problems with the navigation system
ProblemPossible causes/consequences andMSolutions
COMAND does not
resume route guidance
after the journey has
been interrupted.Route guidance is canceled if you interrupt the journey for more
than two hours.
"Interrupting the journey" refers to stopping the vehicle.
"Continuing route guidance" refers to switching COMAND back on
and driving on.
XContinue route guidance manually (Ypage 112).
ProblemPossible causes/consequences andMSolutions
COMAND is unable to
determine the vehicle's
position.COMAND has to redetermine the position of the vehicle if the
vehicle has been transported.
Example:
RAfter transporting the vehicle by ferry
RAfter transporting the vehicle by motorail
XStart the vehicle and pull away.
COMAND determines the vehicle's position. Depending on the
driving situation, this may take some time.
Route guidance may be restricted during the determination of
the vehicle's position.
When positioning is complete, route guidance is resumed with
navigation announcements and route guidance displays.

Procedure and general information
Authorizing a mobile phone (connecting)
If you connect your mobile phone using NFC
( Near Field Communication) the NFC area of
your mobile phone has to touch the NFC logo
on the DVD changer/single DVD drive. The
authorization then starts automatically. The
NFC range varies depending on the mobile
phone and can be identified by the logo. Fur-
ther information; see the manufacturer's
operating instructions.
If you use your mobile phone with COMAND
without NFC, you must search for it
(
Ypage 142) and then authorize it
(
Ypage 142). Depending on the mobile
phone, authorization either takes place by
means of Secure Simple Pairing or by enter-
ing a passkey. COMAND automatically ena-
bles the procedure suited to your mobile
phone. You can recognize Secure Simple Pair-
ing by a code which is displayed in COMAND
and on the mobile phone. You can recognize
the passkey system by the fact that you have to enter a code on the mobile phone and in
COMAND. The mobile phone is always con-
nected automatically after authorization.
If COMAND does not detect your mobile
phone , th
is may be due to particular security
settings on your mobile phone. You can also
start the search procedure and authorization
on the mobile phone (
Ypage 143).
Device-specific information on authorizing
and connecting Bluetooth
®-capable mobile
phones can be obtained from your authorized Mercedes-Benz Center or via the Internet at http://www.mercedes-benz.com/

COMAND at any one time.
De-authorizing (disconnecting) a mobile
phone
The connection is terminated automatically if
you leave the receiver range of COMAND or
deactivate Bluetooth
®on your mobile phone.
If you no longer want the Bluetooth
®connec-
tion to be established automatically, the
mobile phone must be de-authorized (discon-
nected) (
Ypage 145).
