What must I do to be able to be able to use
Bluetooth audio connectivity (AUX BT)?
®
Bluetooth audio transmission must first be activated by
®
entering a setting (AUX Bluetooth
OPTION/SET DISC/AUX'. Mobile phones which support
the corresponding profiles (A2DP/AVRCP) will now
automatically connect these profiles at every start. An
existing connection can be identified by the display of an
additional source AUX BT under DISC.
What functions does Bluetooth
(AUX BT) support?
Functions supported are preset by the scope of func-
tions implemented in the mobile device. Devices without
AVRCP must be operated directly on the device itself.
Minimum scope of functions with AVRCP (Version 1.0)
comprises 'Start Player', 'Pause', 'Next Track' and
'Previous Track'. Some devices additionally support
rewind and fast forward/skipping (operation using the
arrow button on the PCM). Newer devices incorporating
Version 1.3 already support transfer of track names and,
in some cases, further metadata such as artist and
album of the track currently being played, but also the
start of the audio player when the corresponding source
AUX BT is selected on the PCM or advanced player
functions such as 'Shuffle' or 'Repeat'. In all cases,
devices can be connected, disconnected, deleted and
renamed by selecting Devices List.

Why are there different menus for AUX BT?
The different menus are aligned to the ranges of
functions described for various AVRCP versions. Devices
supporting AVRCP1.0 are operated exclusively by using
the arrow buttons. Here the PCM shows only the name of
the device connected. If the device reports AVRCP1.3
support, the PCM displays an advanced menu in which
the metadata transferred (name, artist and album of the
track currently playing) are shown and further player
functions ('Repeat', 'Shuffle', 'Sample') can be operated if
they are supported by the device (Bluetooth
mobile phone).
Why are no metadata (name, artist and album)
displayed in the advanced menu variation AUX BT?
Some devices do not transfer metadata even though
they report AVRCP1.3 support. In these cases the
sections reserved for metadata in the PCM remain
empty.
Why is the source AUX BT not activated after
a system start?
The source AUX BT always needs a Bluetooth
tion to a corresponding mobile phone or Bluetooth
player first of all. This connection is not established
immediately after starting the PCM because first the
telephone profiles (Handsfree or SIM Access Profile)
and then the audio profiles (A2DP, AVRCP) are connect-
ed. In the case of a Bluetooth
function, this must always be connected manually after
a system start.
