Your vehicle is equipped with the harman/
kardon LOGIC7
® Surround Sound system.
You can select between “
LOGIC7®On” and
“
LOGIC7®Off”.
harman/kardon LOGIC7
® Surround Sound
is available for the following operating
modes:

Radio (FM only)

SatRadio*

CD audio

DVD audio (MLP, DTS, PCM and Dolby
Digital audio formats)

MP3 (including PCMCIA memory card)

Aux

DVD video (PCM, DTS and Dolby Digital
audio formats)
i As some DVDs contain both stereo and also
multi-channel audio formats, it may be neces-
sary to set the audio format (
page 66).
i The “LOGIC7®On” function of the harman/
kardon LOGIC7® Surround Sound system per-
mits the playback of discrete 5.1 and stereo re-
cordings with an optimal surround sound
platform for each passenger. Music and films on
CD or audio and video DVDs with high-resolution
surround formats, such as MLP, DTS or Dolby
Digital, are played with optimum sound.
The LOGIC7
® distributes the 5.1 surround infor-
mation over the 12-channel system architecture
to provide the optimum sound in all seats. This
produces the sound characteristics as intended
by the sound engineer during the original record-
ing.
harman/kardon LOGIC7
® converts all two-chan-
nel stereo sound sources into multi-channel sur-
round sound. The surround information stored
during the original recording is read out using
LOGIC7
® and likewise distributed over the
12 channels. No effects are created during the
process, anything that was always on the record-
ing is just made audible again.
Moreover, harman/kardon LOGIC7
® draws the
audible sound source away from the individual
loudspeakers, thus creating a natural 360°
sound platform for each passenger.
i By selecting “LOGIC7® Off”, the playback
of all playable formats is performed as on the ex-
isting medium. Due to the spatial conditions in
the vehicle, optimal sound is not possible in all
seats.
i Discs supporting the above-mentioned au-
dio formats display the following logos

Multisession CDs
On multisession CDs, the content of the
first session determines how COMAND
handles the CD.
If the first session, for example, contains
data in audio CD format and the second
session contains MP3 tracks, COMAND
handles the CD as a conventional audio
CD. This means that the MP3 tracks can-
not be accessed.Similarly, if the first session contains MP3
tracks and the second session contains
d a t a i n a u d i o C D f ormat, COMAND handles
the CD as an MP3 CD. Only the MP3 tracks
can be accessed.
File structure of storage medium
When creating an MP3 storage medium,
you can organize MP3 tracks into folders.
A folder can also contain additional fold-
ers. A storage medium may have a maxi-
mum of 255 folders in total. A maximum of
255 tracks and 255 folders are permissible
per folder. A maximum of 4000 tracks in
total are permissible per storage medium.
Track names and folder names
When creating an MP3 storage medium,
you can assign names to the MP3 tracks
and to the folders.
COMAND uses these names in MP3 mode
for the corresponding display. Empty fold-
ers or folders containing data other than
MP3 tracks will not be displayed by
COMAND.
If MP3 files are stored in the root directory
itself, the root directory also counts as a
folder. COMAND will then display the root
directory name as a folder name.
