Procedure and general information
Searching for and authorizing (connect-
ing) a mobile phone
Before using your mobile phone with Audio
20/COMAND for the first time, you will need
to search (
Ypage 229) for the phone and
then authorize it (
Ypage 229). Depending on
the mobile phone, authorization either takes
place by means of Secure Simple Pairing or by
entering a passkey. Audio 20/COMAND
automatically makes the system suitable for
your mobile phone available. You can recog-
nize Secure Simple Pairing by a code which is displayed in Audio 20/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 Audio 20/
COMAND. The mobile phone is always con-
nected automatically after authorization.
If Audio 20/COMAND does not detect your
mobile phone, this 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 230).
Device-specific information on authorizing
and connecting Bluetooth
®-capable mobile
phones can be found on the Internet at
http://www.mercedes-benz.com/
connect.
You can authorize up to 15 mobile phones.
Only one mobile phone can be connected to
Audio 20/COMAND at any one time.
De-authorizing (disconnecting) a mobile
phone
