Multi-session CDs
For multi-session CDs, the content of the first
session determines how COMAND Online will
process the CD. COMAND Online plays only
one session and gives priority to the audio CD
session.
If possible, only play CDs on COMAND Online
that have been written in one session.
File structure of a disc
When you create a disc with compressed
music files, the tracks can be organised in
folders. A folder may also contain subfolders.
(MP3 mode only)
option is
The disc may contain no more than eight
directory levels. Files beyond the eighth level
will not be recognised by the system.
i
COMAND Online loads up to 15,000
tracks from the SD memory card or USB
storage medium.
Track and file names
When you create a disc with compressed
music files, you can assign names to the
tracks and folders.
COMAND Online uses these names accord-
ingly for the display. Folders that contain data
other than MP3 or WMA tracks are not dis-
played by COMAND Online.
If MP3 or WMA files are stored in the root
directory itself, the root directory will also be
treated as a folder. COMAND Online will then
show the name of the root directory as the
folder name.
You should observe the following when
assigning track names:
track names must have at least one char-
R
acter.
track names must have the extension
R
"mp3" or "wma".
there must be a full stop between the track
R
name and the extension.
Example of a correct track name:
"Track1.mp3".
