MP3 mode
You can also use this car sound sys-
tem to play CD-Rs and CD-RWs that
contain MP3 music files.
MP3 is a process developed by the
Fraunhofer Institute for compressing CD
audio data. Compression allows data to
be reduced to around 10% of their orig-
inal size without a noticeable loss in
quality (at a bit rate of 128 kbit/s). If a
lower bit rate is used to convert CD au-
dio data to MP3, you will be able to cre-
ate smaller files but this will be accom-
panied by a loss in audio quality.

Preparing an MP3-CD

The various combinations of CD burn-
ers, CD burning software and CD blanks
may lead to problems arising with the
device’s ability to play certain CDs. If
problems occur with your own burned
CDs, you should try another brand of
CD blank or choose another colour of
CD blank. To avoid problems when play-
ing CDs, you should not burn CDs at
speeds greater than 16-speed.
The format of the CD must be ISO 9660
Level 1 / Level 2 or Joliet. Other formats
cannot be played reliably.
You can create a maximum of 253 di-
rectories on a CD. You can use this de-
vice to access each of these directo-
ries.
Regardless of the number of directories
on the CD, the device can handle up to
65,535 MP3 files on a single CD - even
if they are all stored in one directory.
This device supports as many subdirec-
tories as your burner software can cre-
ate despite the fact that the maximum
directory depth defined by the ISO 9660
standard is only 8.

You can name each directory using a
PC. The device is capable of displaying
the directory name. Name the directo-
ries and tracks/files using your CD burn-
er software. The software’s instruction
manual will provide details on how to
do this.
