Warning!
Only carry out the following when the vehicle
is stationary:
R Inserting a disc/device
R Ejecting a disc/device
There is
a risk of accident by being distracted
from road and traffic conditions if you load a
disc/device while the vehicle is in motion.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet (approximately
14 m) every second. Notes about MP3 mode

Multisession CDs For multisession CDs, the first session type
of the CD determines how COMAND will
process the CD.
For example, if the first session type is
according to the audio CD standard and the
second session type is according to the data
CD standard containing MP3/WMA tracks, COMAND will treat the CD as a conventional
audio CD. This means that it is only possible
to
access

the audio CD tracks. Access to the
MP3/WMA tracks is not possible.
Similarly, if the first session type is according
to the data CD standard containing MP3/
WMA tracks and the second session type is
according to the audio CD standard,
COMAND will treat the CD as a data CD. This
means that it is only possible to access the
MP3/WMA tracks. Access to the audio CD
tracks is not possible.
File structure on a disc When you create an audio disc, the tracks can
be
organized

in folders. A disc may contain a
maximum of 4000 tracks.
The directory depth may not exceed a
maximum of 8 levels. The system will ignore
files in lower levels.
Notes on USB storage media Do not store data other than audio data on a
USB storage medium. Doing so will increase
the
time

required to initialize the USB storage
medium.
A maximum of 8 directory levels with up to
4000 tracks each are supported.
For information on connecting USB storage
media to the built-in USB socket in the glove
box see ( Y page 72).
Track and folder names When you create an audio medium, you can
assign names to the tracks and folders.
COMAND uses these names for the
corresponding display. Empty folders or
folders which contain data other than MP3/
WMA tracks are not displayed by COMAND.
If MP3/WMA files are saved in the root
directory itself (uppermost directory on
storage medium), the root directory will also
be treated as a folder. COMAND will then
show the name of the root directory as the
folder name.COMAND audio CD/audio DVD/MP3

i
Audio DVDs differ from recordable DVD-
R and DVD-RW discs.
Data on audio DVDs are stored either in
uncompressed format or in lossless
compressed format. The sound quality on
audio DVDs is therefore better than on
recordable DVDs that contain MP3 data
because the
MP3 format uses a lossy type of
compression.
You cannot delete data from or record
additional data to commercially available,
prerecorded audio DVDs.
Please note the following information about
CDs/DVDs and pay special attention to the
notes on copied and/or self-written CDs/
DVDs.
i The last track on many audio DVDs does
not contain audio data. COMAND will then
change to the next medium. This behavior
is system-induced and does not indicate a
system malfunction. Notes about CDs/DVDs
i Audio CDs with copy protection are not
compatible with

the CD audio standard and
therefore may not be able to be played by
COMAND.
There may be playback problems when
playing copied discs.
There is a large variety of discs, disc-writing
software and writers available. This variety
means that there is no guarantee that the
system will be able to play discs that you
have written/copied yourself.
There may be playback problems if you use
CD-R or CD-RW type discs you have copied
yourself with a storage capacity of more
than 700 MB. These CDs are not
compatible with currently applicable
standards.
! Do not affix stickers or labels to the discs.
These could peel away and damage COMAND. COMAND is designed to hold
discs which comply with the IEC 60908
standard.
You

can therefore only use discs
with a maximum thickness of 1.3 mm.
If you insert thicker discs, e.g. those that
contain data on both sides (DVD on one
side and audio data on the other), they
cannot be ejected and can damage
COMAND.
Do not use CDs with a diameter of 8 cm.
Attempting to play discs with a diameter of
8 cm or playing such discs with an adapter
may cause damage COMAND.
Such damages are not covered by the
Mercedes-Benz Limited Warranty.
Only use round discs with a diameter of
12 cm.
Notes about handling CDs/DVDs R
Only hold discs by the edge.
R Handle discs carefully to prevent playback
problems.
R Avoid getting scratches, fingerprints and
dust on discs.
R Clean discs from time to time with a
commercially-available cleaning cloth. Do
not wipe them with a circular motion, but
only in straight lines from the center
outwards.
R Only use

a pen designed for such a purpose
to label discs.
R Place discs back in their boxes after use.
R Protect discs from heat and direct sunlight. Inserting/ejecting CDs and DVD
G
Observe Safety notes, see page 162.
i If the CD/DVD has a printed side, this
must face upwards when the CD/DVD is
inserted. If neither side is printed, the side
to be played should face downwards. COMAND audio CD/audio DVD/MP3
