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.

Safety instructions
G Warning
COMAND is classified as a Class 1 laser
product. You must not open the casing.
There is a risk of exposure to invisible laser
laser radiation if you open the casing, or if
the casing is faulty or damaged.
COMAND does not contain any parts that
you are able to maintain yourself. For safety
reasons, all maintenance work must be car-
ried out by qualified technicians.
G Warning
Only carry out the following when the vehi-
cle is stationary:
Inserting a disc
Ejecting a disc
There is a risk of accident by being distract-
ed from road and traffic conditions if you
load a CD/DVD while the vehicle is in mo-
tion.
Notes on MP3 mode

53 Audio
CD audio/DVD audio and MP3
Please note the following when assigning
track names:
Track names must contain at least one
character.
Track names must have the extension
“mp3”.
A period must appear between the
track name and the extension.
i COMAND does not support ID3 tags.
Permissible MP3 formats
COMAND supports the MPEG1 audio
layer 3 format.
i In everyday speech, this format has been re-
placed by the designation “MP3”.
Permissible bit and scan rates
Fixed and variable bit rates from
32 kbps to 320 kbps
Scan rates from 8 kHz to 48 kHz
i Only 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 result in impaired
sound quality. This is particularly true if the sur-
round sound function has been activated.
Notes on copyright
The music tracks that you can create for
playback 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.
Notes about audio DVD discs
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.
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 com-
pressed format. The sound quality on au-
dio 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 commer-
cially available, prerecorded audio DVDs.
Please note the following information
about CDs/DVDs and pay special atten-
tion to the notes on copied and/or self-
written CDs/DVDs.
Other readable audio formats
COMAND can also read music files in the
WMA (Windows
® Media Audio), AAC (Ad-
vanced Audio Coding) and WAV (Waveform
Audio Format) formats.
i If other music files are stored in these audio
formats on a storage medium, in addition to MP3
files, the loading process may take longer before
the first track is played.

54 Audio
CD audio/DVD audio and MP3
i Discs with copy protection do not comply
with the CD audio standard and in some cases
cannot be played by COMAND.
When playing copied discs, problems may occur
with the playback.
A wide variety of discs, disc writing software and
writers are available. Due to this variety we can-
not guarantee that the system will be able to play
discs that you have written/copied yourself.
There may be playback problems with user-
burned CDs with a storage capacity of more than
700 MB. These CDs do not meet current valid
standards.
i When playing a DVD audio, it may be the
case with numerous albums that the last track
does not contain any music and COMAND
switches to the next track. This is due to the pro-
duction method and does not imply a fault with
the unit.
! Do not attach stickers or labels of any kind
to discs. They may come loose and damage
COMAND.
COMAND has been designed for discs meeting
the requirements of standard EN 60908. There-
fore, only discs with a maximum thickness of
1.3 mm can be used.
If a thicker disc is inserted, e.g. one which stores data on both sides, (DVD on one side, audio data
on the other side), this cannot be ejected and
COMAND will be damaged.
Do not use 8 cm diameter discs, not even with an
adapter. Only use round, 12 cm diameter discs.
i COMAND can play audio CDs with the high-
resolution surround format.
Only touch the discs at the edges.
Handle discs with care in order to pre-
vent malfunctions during playback.
Avoid scratching, leaving fingerprints
and dust on the discs.
Clean the discs occasionally with a
commercially available cleaning cloth.
Always wipe in a straight line from the
inside outwards, never in a circular mo-
tion.
The discs must only be labelled using
pens specially designed for this pur-
pose.
After use, put the discs back into the
box.
Protect the discs from heat and direct
sunlight.
i If the CD/DVD is printed on one side, this
side must face upwards when loaded. If neither
side is printed, the side to be played must face
downwards.
The system may not be able to play copy-protect-
ed CDs/DVDs.
