● Be ar in mind th
at being underground, in
tunnels, in areas with tall buildings or moun-

you switch to Radio mode, the available
frequency bands (FM, AM 1)
and DAB 1)
) are in-
itially displayed in the bottom line of the
screen ››› Fig. 10. If the RADIO unit button is
pr e
s
sed again, more features for the radio re-
ceiver will be displayed.
You can use any of the following:
● Searching for the next station.
● Turning a stored station back on.
● Switching on the TP function ›››

The station that you are currently listening to
is shown in the middle of the screen. For sta- tions compatible with RDS, if the reception
quality is
sufficient, the station name may be
displayed instead of its frequency, e.g. RA-
DIO 21.
RDS and automatic station tracking RDS is a radio data service that allows the
dis
p
lay of the station name, automatic sta-
tion tracking and the TP function (traffic infor-
mation station ››› page 8).
With the automatic station tracking the unit
always switches to the frequency that offers
the best reception of the current radio station
as the vehicle travels from one area to the
next. If the reception is poor, the unit may be
muted for a short time as it searches for alter-
native frequencies (AF).
RDS is not available everywhere or on every
FM radio station.
Depending on the country and the unit, the
RDS and switching to alternative frequencies
(AF) may be deactivated in the system set-
tings ›››
page 18. 1)
This depends on the country and unit in question.

Audio mode
CDs recorded in UDF or Direct CD format can-
not be p
l
ayed. Under Windows Vista ®
ensure
that the correct format is selected.
The unit may be unable to read individual
tracks or the entire data medium due to the
data medium configuration or the devices
and programs used for recording. Informa-
tion about the best ways to create audio files
and data media (compression rate, ID3 tag
etc.) can be found on the Internet.
Due to the larger quantity of data, the unit
takes longer to read a data medium contain-
ing compressed audio files (MP3) than a
“normal” audio CD. Complex folder struc-
tures can also slow down the reading of a da-
ta medium.
Playlists only determine a certain playing or-
der. There are no files stored in a playlist. The
unit will not play a playlist if the files are not
stored on the data medium at the locations
referred to by the playlist (relative file paths). Playing order of files and folders

Example of an MP3 CD structure. Audio files
on dat
a medi
a are often sorted
by folders and playlists to determine a
certain playing order.
Tracks, folders and playlists on a data medi-
um are each sorted by name in alphanumeric
order.
Subfolders are treated like folders and num-
bered in accordance with the sequence on
the CD.
