WarningG
In order to avoid distraction which could
lead to an accident, the driver should insert
CDs with the vehicle at a standstill and oper-
ate the audio system only when road, weath-
er and traffic conditions permit.
Bear in mind that at a speed of just 30 mph

!
Do not attach labels of any type to the
CD. They may become detached and
damgage the drive.
Only use CDs, which bear the label
shown and that conform to the com-
pact digital audio standard
(IEC 60908).
Do not play single-CDs (80 mm) with an
adapter. Only use round, 12 cm diame-
ter CDs.
!
Your CD drive has been designed to
play CDs which correspond to the IEC
60908 standard. Therefore only CDs
not exceeding a thickness of 1.3 mm
can be used.
If you insert thicker data carriers, e.g.
ones that have data on both sides (one
side with DVD data, the other side with
audio data), they cannot be ejected
and will damage the drive.

The COMAND CD drive may not be able

Inserting a second CD in the slot with
another CD still loaded will cause dam-
age to the CD drive not covered by the
Mercedes-Benz Limited Warranty.

Permissible MP3 CDs
In MP3 mode COMAND can read CD-R and
CD-RW CDs.
Permissible file systems
The permitted file system is
ISO9660/Joliet for CD-R and CD-RW.Multi session discs
With multi session discs, the content of the
first session determines how COMAND
treats the CD.
For example, if the first session contains
data in audio CD format and the second
session contains data in MP3 format,
COMAND will treat the CD as a conven-
tional audio CD.
File structure
When creating an MP3 CD, you can orga-
nize MP3 tracks into folders. A folder can
also contain additional folders.
A CD may have a maximum of 255 folders
in total. A maximum of 255 tracks are per-
missible per folder.Mathematically a maximum of 65025
tracks would result. However, this amount
is usually not reached since MP3 requires
approx. 1 MB storage per minute recorded.
Track names and folder names
When creating an MP3 CD, you can assign
names to the MP3 tracks and folders.
COMAND uses these names in MP3-mode
for the corresponding display.
Please note the following when assigning
track and folder names:
Track and folder names must contain
at least 1 character.
Track names may contain up to fifty
characters. If a track name exceeds
this character limit, COMAND will not
be able to display it in full.
Tips on creating MP3 CDs
i
CDs, software and hardware for writing
audio data to CDs are widely available.
Therefore, we cannot guarantee that
COMAND will be able to play every
user-written CD.
Problems may be encountered during
playback of user-written CDs with a
storage capacity of more than 700 MB.
These CDs do not meet valid standards
as of this printing.
52 Audio
MP3 operation
Track names must have the file exten-
sion “mp3”.
A period must appear between the
track name and the file extension.
Example of a correct track name:
Track1.mp3
In the example, the track name con-
tains six characters, followed by a peri-
od and the file extension “mp3”.
Empty folders or folders containing data
other than MP3 tracks will not be dis-
played 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. Permissible MP3 formats
COMAND supports the
MPEG1 Audio Layer 3 format.
Permissible bit and scan rates
Fixed and variable bit rates up to
320 kbps
Scan rates from 24 kHz - 48 kHzThe music tracks that you can create for
play back in MP3 mode are generally copy-
right-protected under applicable interna-
tional and national laws.
In many countries, the reproduction of
copyrighted material is not permitted,
even if only for personal use, without the
express prior consent of the copyright
holder.
Please check the current copyright laws
for your country and comply with them.
These restrictions do not apply for exam-
ple to your own compositions and record-
ings, or for recordings for which
authorization has been obtained from the
copyright holder.
i
COMAND does not support ID3 tags.
Tips on creating MP3 tracks
i
In everyday speech, this format has
been replaced by the designation
“MP3”.
i
It is recommended to use MP3 tracks
with a bit rate of 128 kbps or higher
and with a scan rate of 44.1 kHz or
higher. Lower rates may impair quality.
This is particularly true if the Sound
function*
LOGIC7 Surround has been acti-
vated.
