Using an MP3
MP3 CD-R Disc
MP3 Format
If you burn your own MP3 disc on a personal computer:
• Make sure the MP3 files are recorded on a
CD-R disc.
• Do not mix standard audio and MP3 files on
one disc.
• Make sure playlists have a .mp3 or .wpl extension,
other file extensions may not work.
• Files can be recorded with a variety of fixed or
variable bit rates. Song title, artist name, and album
are available for display by the radio when
recorded using ID3 tags version 1 and 2.
• 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.
• Make sure to finalize the disc when burning an MP3
disc, using multiple sessions. It is usually better to
burn the disc all at once.
The player is able to read and play a maximum of
99 folders and playlists. Long file names, folder names,
or playlist names can use more disc memory space
than necessary. To conserve space on the disc,
minimize the length of the file, folder, or playlist names.
You can also play an MP3 CD that was recorded
using no file folders. The system can support up to
11 folders in depth, though, keep the depth of the folders
to a minimum in order to keep down the complexity
and confusion in trying to locate a particular folder during
playback. If a CD contains more than the maximum of
99 folders and playlists the player can access and
navigate up to the maximum, but all items over
the maximum are ignored.
Root Directory
The root directory is treated as a folder. If the root
directory has compressed audio files, the directory
displays as F1 ROOT. All files contained directly under
the root directory are accessed prior to any root
directory folders. However, playlists (Px) are always
accessed before root folders or files.
Empty Directory or Folder
If a root directory or a folder exists somewhere in the
file structure that contains only folders/subfolders and no
compressed files directly beneath them, the player
advances to the next folder in the file structure
that contains compressed audio files and the empty
folder does not display.
