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

Notes on programming the remote con-
trol
Canadian radio frequency laws require a
"break" (or interruption) of the transmission
signals after broadcasting for a few seconds. Therefore, these signals may not last long
enough for the integrated garage door
opener. The signal is not recognized during
programming. Comparable with Canadian
law, some U.S. garage door openers also fea-
ture a "break". Proceed as follows:

Problems when programming
If you are experiencing problems programing
the integrated garage door opener on the
rear-view mirror, take note of the following
instructions:
RCheck the transmitter frequency used by
garage door drive remote controlAand
whether it is supported. The transmitter
frequency can usually be found on the back
of the garage door drive remote control.
The integrated garage door opener is com-
patible with devices that have units which
operate in the frequency range of 280 to
433 MHz.
RReplace the batteries in garage door
remote control A. This increases the like-
lihood that garage door remote control A
will transmit a strong and precise signal to
the integrated garage door opener.
RWhen programming, hold remote control
A at varying distances and angles from the
button which you are programming. Try var-
ious angles at a distance between 2and
12 inches (5to 30 cm) or at the same angle
but at varying distances.
RIf another remote control is available for the
same garage door drive, repeat the same
programming steps with this remote con-
trol. Before performing these steps, make
sure that new batteries have been installed
in garage door drive remote control A.
RNote that some remote controls only trans-
mit for a limited amount of time (the indi-
cator lamp on the remote control goes out).
Press buttonBon remote control Aagain
before transmission ends.
RAlign the antenna cable of the garage door
opener unit. This can improve signal recep-
tion/transmission.
