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:
R
track names must have at least one char-
acter.
R
track names must have the extension
"mp3" or "wma".
R
there must be a full stop between the track
name and the extension.
Example of a correct track name:
"Track1.mp3".
Permissible formats
COMAND supports the following formats:
R
MPEG1 Audio Layer 3 (MP3)
R
Microsoft Windows Media Audio V8 and V9
(WMA) without copy protection
Microsoft Windows Media Audio V2, V7, V8
and V9 (WMA)
R
additional music files in AAC format with
the file extensions .aac, .mp4, .m4a
and .m4b, but not copy-protected iTunes
music files with the extension .m4p
i
If, in addition to MP3 files, there are other
music files in these audio formats stored on
the disc, the loading process may require a
longer time before the first track is played.
i
The MP3 audio encoding method is under
licence from Fraunhofer IIS (Institut Integ-
rierte Schaltungen Institute for Integrated
Circuits) and Thomson.

Only use tracks with a bit rate of at least

able deterioration in quality. This is espe-
cially the case if you have activated a sur-
round sound function.

tection in accordance with the applicable
