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 Press CONFIG to open the Settings
menu.Select Radio settings and then RDS
options .
Set RDS to On or Off.
Notice
If RDS is switched off, it will be
automatically switched on again when a radio station is changed (bysearch function or preset button).
Notice
The following options are only
available, if RDS is set to On.
RDS options

If regionalisation is switched off,
alternative frequencies of the stations
are selected without regard to
regional programmes.
