Using an MP3 CD
MP3 Format
The MP3 radio will play both standard audio CDs and
CD-R or CD-RWs. The CD-R/RWs may contain either
standard audio (*.cda) or compressed audio (*.mp3).
Customers who record their own music CD-R/RWs
should be aware of the following:
• The files can be recorded on a CD-R/RW disc with
a maximum capacity of 700 MB.
• The radio will play only compressed audio files
recorded in the *.mp3 format. It also supports
playlists that can be made and saved with popular
MP3 software, in the *.m3u format. The directory,
playlist, and song name must have no more than
64 characters combined, e.g. /DIRECTORY NAME/
PLAYLIST NAME/SONG NAME.MP3. If more than
64 characters are present, the radio will ignore that
song and move to the next one.
• The radio will only play audio from a CD-R/RW,
it cannot record audio.
• The radio does not support DVD audio.
• The radio does not support UNICODE.
• The radio will play a mixed mode CD-R/RW, one
recorded with both *.cda and *.mp3 files.
• The radio supports multi-session discs, but only the
files from the last session will be played.
• There are a total of 20 directories (folders) allowed
on a CD. The file structure can be 4 directories deep
(a folder within a folder, within a folder, etc.).
Anything more than 20 directories will be ignored.
Each directory may have up to 99 files contained
within it. Files not having the *.mp3 extension will not
be played, but still count toward the maximum.
Anything more than the first 99 files within a directory
will be ignored. A single CD may have up to 254 files
and directories. Anything beyond the 254 limit will be
ignored.
• MP3 files must be written to a CD-R/RW in one of the
following industry-standard formats:
• ISO 9660 Level 1
• ISO 9660 Level 2
• Joliet
• Romeo
• ID3 tag information is displayed by the radio,
if available. The ID3 tag information can be either
version 1 or 2. The radio will display a filename, song
name, artist name, album name, directory name, or
playlist name.
If the customer does not follow these guidelines when
recording a CD-R(W), the CD may not play in the radio.
