Using an MP3
MP3/WMA CD-R Disc
MP3/WMA Format
If you burn your own MP3/WMA disc on a personal
computer:
• Make sure the MP3/WMA files are recorded on a
CD-R disc.
• Make sure playlists have a .mp3 or .wpl extension,
other file extensions might not work.
• Files can be recorded with a variety of fixed or
variable bit rates. Song title, artist name, and album
are displayed 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/WMA 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
253 folders, 50 playlists, 20 sessions, and 949 files.
Long file names, folder names, or playlist names may
use more disc memory space than necessary. To
conserve space on the disc, minimize the length of the
file, folder, or playlist names. An MP3/WMA CD-R 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 253 folders, 50 playlists, 20 sessions, and
949 files, the player lets you access and navigate up
to the maximum, but all items over the maximum are
played.
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.
