Several announcement categories
can be selected at the same time.
Notice
DAB announcements can only be
received if the DAB waveband is
activated.
Radio data system (RDS) RDS is a service of FM stations that
considerably facilitates the finding of
the desired station and its fault-free
reception.Advantages of RDS
■ On the display the programme name of the set station appears
instead of its frequency.
■ During a station search the Infotainment system tunes in to
RDS stations only.
■ The Infotainment system always tunes into the best receivable
broadcasting frequency of the set
station by means of AF (Alternative Frequency).
■ Depending on the station that is received, the Infotainment systemdisplays radio text that can contain,
e.g., information about the current
programme.
Configuring RDS To open the menu for the RDS
configuration:
Press CONFIG .
CD 400 / CD 400plus: Select Radio
settings and then RDS options .
CD 300: Select Audio settings and

The traffic announcement is aborted,
but the radio traffic service remains
switched on.
EON (Enhanced Other Networks)
With EON you can listen to radio
traffic announcements even if the
station you have set does not
broadcast its own radio traffic service.
If such a station is set, it is displayed
in black as for radio traffic service stations TP.
Digital audio broadcasting Digital audio broadcasting (DAB) is
an innovative and universal
broadcast system.
DAB stations are indicated by the
programme name instead of the
broadcasting frequency.
General information
■ With DAB, several radio programmes (services) can be
broadcast on a single frequency
(ensemble).
■ Besides high-quality digital audio services, DAB is also able to
transmit programme-associated
data and a multitude of other data
services including travel and traffic
information.
■ As long as a given DAB receiver can pick up the signal sent out by a
broadcasting station (even if the signal is very weak), sound
reproduction is ensured.
■ There is no fading (weakening of the sound) that is typical of AM or
FM reception. The DAB signal is
reproduced at a constant volume.
■ If the DAB signal is too weak to be picked up by the receiver, receptionis interrupted completely. This
incident can be avoided by
activating Auto ensemble linking
and/or Auto linking DAB-FM in the
DAB settings menu.
■ Interference caused by stations that are on nearby frequencies (a
phenomenon that is typical of AM
and FM reception) does not occur
with DAB.
■ If the DAB signal is reflected by natural obstacles or buildings, the
reception quality of DAB is
improved, whereas AM or FM
reception is considerably impaired
in such cases.
■ When DAB reception is enabled, the FM tuner of the Infotainmentsystem remains active in the
background and continually
searches for the best receivable FM stations. If TP 3 103 is activated,
Page 106 of 133

106Radio
traffic announcements of the FM
station which is currently best
receivable are issued. Deactivate TP, if you do not wish DAB
reception to be interrupted by FM traffic announcements.
Configuring DAB
Press CONFIG .
Select Radio settings and then DAB
settings .
The following options are available in
the configuration menu:
■ Auto ensemble linking : with this
function activated, the device switches over to the same service
(programme) on another DAB
ensemble (frequency, if available)
when the DAB signal is too weak to
be picked up by the receiver.
■ Auto linking DAB-FM : with this
function activated, the device
switches over to a corresponding
FM station of the active DAB
service (if available) when the DAB signal is too weak to be picked up
by the receiver.
■ Dynamic audio adaption : with this
function activated, the dynamic
range of the DAB signal is reduced.
That means the level of the loud
sounds is reduced, but not the level of the quiet sounds. Therefore the
volume of the Infotainment systemcan be raised to a point where the
quiet sounds are audible, without
the loud sounds being too loud.
■ Frequency band : after selection of
this option it can be defined which
DAB wavebands are to be received
by the Infotainment system.

Usage ........................................ 108General information
The Infotainment system's CD player
can play audio CDs and MP3/
WMA CDs.
Important information about
audio CDs and MP3/WMA CDsCaution
Under no circumstances place
DVDs, single-CDs with a diameter
of 8 cm or shaped CDs in the audio
player.
You must not put any stickers on
CDs. These discs can get jammed in the CD drive and ruin the player. Replacement of the device will
then be necessary.
■ The following CD formats can be used:
CD-ROM Mode 1 and Mode 2
CD-ROM XA Mode 2, Form 1 and
Form 2
■ The following file formats can be used:
ISO9660 Level 1, Level 2, (Romeo,Joliet).
MP3 and WMA files written in any
format other than listed above may
not play correctly, and their file names and folder names may not
be displayed correctly.
Notice
ISO 13346 is not supported. It may
be required to manually select
ISO 9660 when burning an audio
CD, e.g. with Windows 7.
■ Audio CDs with copy protection, which are not in compliance with
the audio CD standard, may not
play correctly or not at all.
■ Self-recorded CD-Rs and CD-RWs
are more vulnerable to mishandling than prerecorded CDs. Correct
handling, especially in the case of
self-recorded CD-Rs and CD-RWs,
must be ensured. See below.
■ Self-recorded CD-Rs and CD-RWs
may not play correctly or not at all.
In such cases it is not the
equipment that is at fault.
