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
broadcast on a single 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.
● 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 is
improved, whereas AM or FM
reception is considerably
impaired in such cases.
● When DAB reception is enabled,
the FM tuner of the Infotainment
system remains active in the
background and continually
searches for the best receivable
FM stations. If TP 3 157 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.
DAB Announcements
Besides their music programmes, a
lot of DAB stations also broadcast
announcements of various
categories. If you activate some or all
categories, the currently received
DAB service is interrupted when an
announcement of these categories is
made.
