MP3 Format
Burning an MP3 disc on a personal computer:
• Make sure the MP3 files are recorded on a CD-R or
CD-RW disc.
• Do not mix standard audio and MP3 files on
one disc.
• Make sure the CD does not have more than a
maximum of 50 folders, 50 playlists, and 255 files.
• Create a folder structure that makes it easy to find
songs while driving. Organize songs by albums
using one folder for each album. Each folder
or album should contain 18 songs or less.
• Avoid subfolders. The system can support up
to 8 subfolders deep, however, keep the total
number of folders to a minimum in order to reduce
the complexity and confusion in trying to locate a
particular folder during playback.
• Make sure playlists have a .m3u extension as other
file extensions might not work.
• Minimize the length of the file, folder, or playlist
names. Long file, folder, or playlist names, or a
combination of a large number of files and folders,
or playlists can cause the player to be unable to play
up to the maximum number of files, folders, playlists,
or sessions. To play a large number of files, folders,
playlists or sessions, minimize the length of the file,
folder, or playlist name. Long names also take up
more space on the display, potentially getting cut off.
• Finalize the audio disc before burning it. Trying to
add music to an existing disc may cause the disc not
to function in the player.
Playlists can be changed by using the previous and next
folder buttons, the
f
(tune) knob, or the © SEEK ¨
arrows. An MP3 CD-R or CD-RW that was recorded
using no file folders can be played. If a CD-R or CD-RW
contains more than the maximum of 50 folders,
50 playlists, and 255 files, the player can access
and navigate up to the maximum, but all items over
the maximum are not accessible.
