Radio101Radio 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
system displays 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
then RDS options .

Page 103 of 175

Radio103The 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 bebroadcast 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 andtraffic information.
● As long as a given DAB receiver can pick up the signal sent out bya 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,
reception is 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 3 101 is
Page 104 of 175

104Radioactivated, 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 system can beraised 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.

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.

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 withthe 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.
