G
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.
Warning
G
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.
!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.
Do not play single-CDs (80 mm) with an
adapter. Only use 12 cm diameter CDs.

58 AudioMP3 operationFor 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 a MP3 CD, you can organize
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 permissible
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
folder and track names:

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
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.
