Glossary
Apple® CarPlay
CarPlay® is an Apple® standard that allows
important applications of your Apple® device to
be controlled via your PCM display while driving.
The most important applications are making
and receiving calls, messaging, audio playback
and navigation. Other apps are possible. Both
the approval of CarPlay® in individual countries
and the approval of apps for CarPlay® are
exclusively managed by Apple®.
Audio player
An audio player is a software application on a
portable device (e. g. mobile phone) for playing
audio files stored on the device.
Authorisation
In order for a Bluetooth® connection to be
automatically established, the requesting
device must be authorised on the other device.
This authorisation is performed automatically
on some phones, while on others it must be
explicitly performed by the user in the
Bluetooth® device list.

Auto-connect
If two devices have been paired with each other
and are therefore authorised to exchange data,
either device can automatically transmit a
connection request from the application that is
automatically answered by the second device.
It is therefore possible for a Bluetooth® mobile
phone to be automatically connected every time
the car is started. In order for the mobile phone
request to be answered, the requesting system
must be authorised on the mobile phone.
Bluetooth®
Bluetooth® is an industry standard for the
wireless networking of electronic devices over
short distances of maximum 10 metres. It
allows mobile electronic devices such as mobile
phones and PDAs (Personal Digital Assistants)
as well as PCs and peripherals (e. g. keyboards)
to communicate wirelessly with each other,
with Bluetooth® as the interface.

Bluetooth® Advanced Audio Distribution
Profile (A2DP)
Bluetooth® Advanced Audio Distribution Profile
(A2DP) enables digital audio data (e. g. MP3s)
to be streamed wirelessly from a data source
(portable MP3 player or mobile phone) to a
receiver (headphones or vehicle sound system).
It is used by PCM for the BT Audio source.
Bluetooth® Audio
Bluetooth® Audio describes an external audio
source in PCM (similar to iPod® or USB), by
which the audio data stored on a mobile device
can be streamed via Bluetooth® and played via
the PCM sound system. Required Bluetooth®
profiles are A2DP and AVRCP.
CONTENTS
Bluetooth® Audio Video Remote Control
Profile (AVRCP)
The Bluetooth® Audio/Video Remote Control
Profile (AVRCP) enables the remote control
of an audio player on a mobile device
(e. g. portable MP3 player or mobile phone).
Supported functions depend heavily on the
actual implementation on the mobile phone or
Bluetooth® player in question. The minimum
functionality comprises 'Start Player', 'Pause',
'Next Track' and 'Previous Track'. Newer devices
already support the transfer of some metadata
(name, artist and album of the track currently
being played) and even the launching of
the audio player when the relevant BT Audio
source is selected on PCM, or advanced player
functions such as 'Shuffle' and 'Repeat'.
