COMAND audio CD/audio DVD/MP3
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 commercially 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.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 soft-
ware 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 ap-
plicable standards.
!Do not affix stickers or labels to the discs.
These could peel away and damage COMAND.
COMAND is designed to hold discs which com-
ply with the IEC 60908 standard. You can there-
fore 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 discs with an 8-cm diameter, even if
they have an adapter.
Only use round discs with a 12-cm diameter.

Notes about handling CDs/DVDs

Only hold discs by the edge.

Handle discs carefully to prevent play-
back problems.

Avoid getting scratches, fingerprints
and dust on discs.

Clean discs from time to time with a
commercially-available cleaning cloth.
Do not wipe them with a circular mo-
tion, but only in straight lines from the
center outwards.

Only use a pen designed for such a pur-
pose to label discs.

Place discs back in their boxes after
use.

Protect discs from heat and direct sun-
light.
Inserting CDs and DVDs Loading the CD/DVD changer
The CD/DVD changer can hold up to a to-
tal of 6 audio CDs or DVDs.
1Disc slot
2Load button (all magazine trays)
3Magazine tray buttons 1 – 6
Warning!G
Only insert a CD or DVD when the vehicle is
stationary. There is a risk of accident by be-
ing distracted from road and traffic condi-
tions if you load a CD/DVD 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 (approximate-
ly 14 m) every second.
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.
iEach magazine tray button3 indicates the
status of the corresponding magazine tray by
means of an LED.

LED off = magazine tray is empty

LED constantly lit = magazine tray is loaded

LED flashes = CD/DVD changer requesting
disc to be loaded

15 seconds COMAND resumes playback of the
last disc.
iCOMAND supports commercially available
PCMCIA cards or PCMCIA card adapters with
storage media that may not be designed for the
temperatures which occur in the vehicle. You
should therefore remove the PCMCIA card from
the vehicle when not in use since extreme tem-
peratures could damage these devices.
