After you switch to Radio mode, the available
frequency bands (FM, AM and DAB) are ini-
tially displayed in the bottom line of the
screen ›››
Fig. 2. After roughly 5 seconds, they
are replaced by the “station buttons”
››› Fig. 3. Stations can be stored to the station
buttons ›››
page 12. The station that is playing will appear in the
centre of
the screen. For stations with RDS,
the name of the station will appear instead of
its frequency if reception is good enough, for
example RADIO 1.
RDS and automatic station tracking
(only in FM) RDS is a radio data service which makes it
pos
s
ible to receive additional services such
as the display of station names, automatic
station tracking (AF) and the TP function (Traf-
fic Program ››› page 16).
With automatic station tracking, when the ve-
hicle is in motion the station always changes
to the frequency with the best reception in
that moment. If the reception is poor, the unit
may be muted for a short time as it searches
for alternative frequencies (AF).
RDS does not exist everywhere nor is it avail-
able for all stations.
Depending on the country and the unit, it is
possible that the RDS and the alternative fre-
quencies (AF) are deactivated ›››

››› page 23. Restrictions and notes
C
ont
amin
ation, exposure to high tempera-
tures and mechanical damage may render a
data medium unusable. Observe the manu-
facturer's instructions on the data medium.
Variations in the quality of data media pro-
duced by different manufacturers may lead to
problems during playback.
Please observe copyright laws. CDs recorded in UDF or Direct CD format can-
not be pl
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. Compatibil-
ity with all encoding/recording software, re-
cording devices and recording media cannot
be guaranteed. Information can be found on
the internet regarding the best ways to create
audio files and data media (compression
rate, ID3 tag etc.).
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).
