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 80).
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.
You must observe the following when
assigning track names:
R Track names must have at least one
character.
R Track names must have the extension
“mp3” or “wma”.
R There must be a period between the track
name and the extension.
Example of a correct track name:
Track1.mp3
Compatible file systems and
compression methods
COMAND supports the following formats:
R MPEG1 Audio Layer 3 (MP3) 25
R Microsoft Windows Media Audio (WMA) V2,
V7, V8 or V9 that are not copy-proof
Bit and sampling rates
MP3
COMAND supports MP3 files of the following
types:
R Fixed and variable bit rates from
32 kbit/s up to 320 kbit/s
R Sampling rates of 24 kHz to 48 kHz
WMA (Windows Media ®
Audio)
Windows Media ®
Audio (WMA) is an audio
data compression technology developed by
Microsoft ®
.
COMAND supports WMA files of the following
types:
R Fixed and variable bit rates from 5 kbit/s
up to 384 kbit/s
R Sampling rates of 8 kHz to 48 kHz
COMAND does not support WMA files of the
following types:
R DRM (Digital Rights Management) coded
files
R variable bit rates
R Losless Settings
R WMA Pro

loss of sound quality. This applies in
particular when you have switched on 3-D
sound.
Notes on copyright
The music tracks that you create and play
back in the MP3 or WMA format are generally
subject to copyright protection in accordance
with the applicable international and national
regulations.
In many countries, reproductions are not
permitted without the prior consent of the
copyright holder, not even for private use.
Make sure that you know the applicable
copyright regulations and that you comply
with these.
If you own these rights yourself, e.g. for your
own compositions and recordings, or the
copyright holder has granted you permission,
these restrictions do not apply.
Notes about audio DVD operation
COMAND can playback commercially
available, prerecorded audio DVDs that bear
the following label. You will usually find the
label on the DVD booklet, the inlay, or the
DVD itself.
iAudio 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.
iThe 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
iAudio 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
ROnly hold discs by the edge.
RHandle discs carefully to prevent playback
problems.
RAvoid getting scratches, fingerprints and
dust on discs.
RClean 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.
ROnly use a pen designed for such a purpose
to label discs.
RPlace discs back in their boxes after use.
RProtect discs from heat and direct sunlight.
Inserting/ejecting CDs and DVDs
GObserve Safety notes, see page 176.
iIf 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.
