Extra Information

Radio 23
Switching RDS on and off
Set RDS to On or Off. The following
advantages result through activating
RDS:
■ On the display the program name
of the set station appears instead of
its frequency.
■ 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,
for example, information about the
current program.
Switching regionalization on and off
RDS must be activated for
regionalization. At certain times some
RDS stations broadcast regionally
different programs on different
frequencies.
1. Set Regional to On or Off. Only
alternative frequencies (AF) with
the same regional programs are
selected.
2. If regionalization is switched off,
alternative frequencies of the
stations are selected without
regard to regional programs.
RDS scrolling text
Some RDS stations use the lines for
indicating the name of the program to
indicate additional information.
During this process the program
name is hidden. To block out the
display of the additional information,
set text scroll freeze to On.
DAB
The digital radio system DAB (digital
audio broadcasting) is a universal
broadcast system.
DAB stations are indicated by the
program name instead of the
broadcasting frequency.
General information
■ With DAB, several radio programs
(services) can be broadcast on
a single frequency.
■ Besides high-quality digital audio
services, DAB is also able to
transmit program-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 vague to be
interpreted by the receiver,
reception is interrupted completely.
This incident can be avoided by
activating Auto ensemble linking
and/or Auto linking DAB-FM 3. See
“Configuring DAB” below.
■ Interference caused by stations on
nearby frequencies (typical of AM
and FM reception) does not occur
in connection with DAB.
■ If the DAB signal is reflected by
natural obstacles or buildings, the
reception quality of DAB is
