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.
