● During a station search, the Infotainment system tunes in to
RDS stations only.
● The Infotainment system always tunes into the best receivable

(alternative frequency).
● Depending on the station that is received, the Infotainment
system displays radio text that
can contain e.g. information on
the current programme.RDS configuration

Digital audio broadcasting
DAB broadcasts radio stations
digitally.
DAB stations are indicated by the
programme name instead of the
broadcasting frequency.
General information ● With DAB, several radio programmes (services) can be
broadcasted on a single
ensemble.
● Besides high-quality digital audio
services, DAB is also able to
transmit programme-associateddata 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 bya broadcasting station (even if
the signal is very weak), sound
reproduction is ensured.
● In the event of poor reception, the
volume is reduced automatically
to avoid the output of
disagreeable noises.
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 DAB-DAB
Linking and/or DAB-FM Linking
in the DAB menu (see below).
● 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 isimproved, 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 FM stations with
the best reception. If TP 3 103 is
activated, traffic announcements
of the FM station with the best
reception are issued. Deactivate
TP if DAB reception should not
be interrupted by FM traffic
announcements.
