Safety Instructions
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
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet (approximate-
ly 14 m) every second.
WarningG
The CD drive is a Class 1 laser product.
There is a danger of invisible laser radiation
when you open or damage the cover.
Do not remove the cover. The CD drive does
not contain any parts serviceable by the us-
er. For safety reasons, have any necessary
service work performed by qualified person-
nel.
Tips on data storage media
!
Do not attach labels of any type to the
CD. They may become detached and
damage the drive.
Do not play single CDs (80mm) with an
adapter. An adapter could become
stuck and damage the drive. Only use
12 cm diameter 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 will become stuck and
damage the drive.
Data carriers which contain data on
both sides can cause playback prob-
lems because the storage layers are
thinner than one-sided data carriers.

MP3 operation
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
folder and track names:
Per folder a maximum of 1800 charac-
ters are available for title and folder
names combined.
Exceeding this number, COMAND can-
not display all titles and folders.
Track and folder names must contain
at least 1 character.
Track names may contain up to fifty
characters. If a name exceeds this
character limit, COMAND will not be
able to display it in full.
Track names must have the extension
“mp3”.
A period must appear between the
track name and the file extension.
Example of a correct track name:
Track1.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 kHz
.
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
w i t h a b i t r a t e o f 1 2 8 k b p s o r h i g h e r a n d
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 activated.
