DAB digital radio mode
Introduction
Some units also have a DAB radio receiver. DAB is a broadcasting standard
for the overland reception of radio programmes

The radio station is responsible for the content of the broadcast informa-
tion.
Operation
In Europe, digital radio has two DAB broadcasting standards, DAB+ and
DMB radio. The digital radio broadcasts on frequencies from waveband III
(174 MHz to 240 MHz) and waveband L (1452 MHz to 1492 MHz).
The frequencies of both bands are called “channels”, and are abbreviated
accordingly (for example, 12 A).
In one channel, several DAB stations join together with the additional avail-
able services, forming an “Ensemble”.
These additional services are used to send additional information to the ra-
dio (e.g. news, sports, weather, warnings, etc.). DAB is currently
not available in all areas. When the DAB radio mode is ac-
tive, in areas where DAB is not available, the symbol of an aerial crossed
out is displayed.
Depending on the settings, in DAB mode incoming DAB messages are
played (for example, news, sport, weather forecasts, warnings, etc.)
⇒ page 27.
As a general rule, while you are driving the DAB tracking function changes
to the channel of the currently playing digital station with the best recep-
tion. This permits additional settings to be made ⇒ page 27.
Note
If the symbol of a crossed-out aerial is displayed “”, this indicates that
the currently playing digital station on the channel selected is no longer
available in this location.
Note
Some digital stations also offer the radio text service. This is activated in
exactly the same way as for a conventional radio station ⇒ page 21.
Note
The DAB radio receiver is compatible with the DAB and DAB+ standards.

Switching on additional stations on the DAB station list
If there are additional stations for a DAB station, an arrow is displayed be-
fore the name of the station .
If one of these stations is switched on from the list, first another list is
opened for you to select whether you wish to listen to the main station o
one of the additional stations.
Updating the DAB station list
While the stations are being updated, the unit searches the dial for availa-
ble ensembles in the region.
Even though the unit is not operating in DAB mode, the list of DAB stations
will be automatically updated.
The list of digital stations can also be updated manually.
● Press the Update
function button in the DAB station list
⇒ Fig. 21.
● Wait until the update has completed.
● Alternatively: press the Cancel
function button.
While the stations are being updated, a pop-up window opens and the vol-
ume of the DAB radio is muted.
The pop-up window closes once the update is complete.
The currently playing DAB station is not modified with the update. Displays and function buttons in the DAB station list
Display: Meaning Ensemble: ensemble closed.
Ensemble: ensemble open. Radio DAB A-x: DAB station in an open ensemble. Radio DAB A-x: the DAB station offers other additional stations. Radio DAB A-x: temporarily without reception of the DAB station. Radio DAB A-x (FM): station received on FM band. Temporarily unable to
receive DAB.

DAB settings
● In Radio mode, press the SETUP button.
● In the Radio setup menu, press the DAB settings button.
Function button: Result DAB announcements: the incoming DAB messages are played with the DAB
radio mode on. If there is no FM station temporarily available and the TP
function is on, the DAB traffic reports are played in any operating mode as
TP reports ⇒ page 21.
DAB tracking: tracking of activated programmes. To switch off, untick the
check box.
Automatic switch DAB-FM: The unit may be set to switch to the FM frequency
band when required for automatic station tracking.
DAB programme tracking and switching from DAB to FM
The DAB and FM station should broadcast the corresponding station identi-
fier in order to run programme tracking in several frequencies.
Page 29 of 112
28Audio mode
When the DAB reception is poor, the unit tries to find and tune into the cor-
responding DAB station in the FM band.
As long as the station is broadcast through the FM band, (FM) is displayed
behind the station name. When the station can be found again in DAB, the
(FM) display disappears.
If the reception of a DAB station is poor and it cannot be found on FM either,
the radio volume is muted.
The DAB programme tracking function can be switched off if you do not wish
to change stations automatically, as the loss of signal is for a short time on-
ly, for example, when driving through a tunnel.

Media mode Introduction
“Media sources” are audio sources containing audio files on various differ-
ent data media (e.g. CD, memory card, external MP3 player). These audio
files can be played by the radio and navigation system from its correspond-
ing drives or audio input sockets (internal CD player, memory card slot, ME-
DIA-IN interface, AUX-IN, etc.).
The supported file formats listed are collectively referred to below as “audio
files”. A CD containing audio files of these types is referred to as an “audio
data CD”.
Additional Information:
● Safety notes ⇒ page 6
● Unit overview ⇒ page 8
● Multimedia interface ⇒ page 42
WARNING
● Inserting a data medium while you are driving could distract you from
the road and result in accident.
● The functions described below depend on the device used. There may
be differences with certain devices.

Bluetooth ®a)
.- The external audio source must be com-
patible with the Bluetooth A2DP profile.
AUX. External audio source.– Audio output is possible with a 3.5 mm
jack connector ⇒ Fig. 1 9.MDI. External data medium.- Compatible with MEDIA-IN multimedia in-
terface ⇒ page 42.

Restrictions and notes
Dirt, high temperatures or mechanical damage may damage the data medi-
ums. Observe the manufacturer's instructions.
Page 31 of 112
30Audio mode
Variations in the quality of data media produced by different manufacturers
may lead to problems during playback.
Observe copyright laws!
CDs recorded in UDF or Direct CD format cannot be played. 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. Information can be found on the Internet on the best ways to cre-
ate audio files and data media (compression rate, ID3 tag etc.).
Due to the larger quantity of data, it takes longer to read a data medium
containing compressed audio files (MP3, WMA etc.) than a “normal” audio
CD. Complex folder structures can also slow down the reading of a data me-
dium.
Playlists only determine a certain playing order. There are no files stored in
a playlist. The unit will not play a playlist if the files are not on the data me-
dium at the locations referred to by the playlist (relative file paths). Playing order of files and folders
Fig. 23 Possible struc-
ture on an audio data CD.
Audio files on data media are often organised by means of folders and
playlists to determine a certain playing order.
Tracks, folders and playlists on a data medium are sorted by name in alpha-
numeric order.

marked in the Media setup menu, and in the Media Selector , the MDI
source or the AUX2 source (depending on the vehicle configuration) is dis-
played as active, even if there is no device connected to this source. There-
fore, this option should not be switched on, except in the cases shown (see
