Infotainment System 7-15
Compressed Audio or Mixed Mode
Discs
The radio can play discs that
contain both uncompressed CD
audio and MP3 files. If both
formats are on the disc, the radio
reads all MP3 files first, then the
uncompressed CD audio files.
CD‐R‐ or CD‐RW‐Supported File
and Folder Structure
The radio supports:
. Up to 50 folders.
. Up to 8 folders in depth.
. Up to 50 playlists.
. Up to 255 files.
. Playlists with an .m3u or .wpl
extension.
. Files with an .mp3, .wma, or .cda
file extension.
Root Directory
The root directory is treated as a
folder. Files are stored in the root
directory when the disc or storage
device does not contain folders.
Files accessed from the root
directory of a CD display as
F1 ROOT.
Empty Folder
Folders that do not contain files are
skipped, and the player advances to
the next folder that contains files.
Order of Play
Compressed audio files are
accessed in the following order:
. Playlists (Px).
. Files stored in the root directory.
. Files stored in folders in the root
directory.
Tracks are played in the following
order:
. Play begins from the first track
in the first playlist and continues
sequentially through all tracks
in each playlist. When the last
track of the last playlist has
played, play continues from the
first track of the first playlist.
. Play begins from the first track
in the first folder and continues
sequentially through all tracks in
each folder. When the last track
of the last folder has played,
play continues from the first
track of the first folder.
File System and Naming
The song name that displays is the
song name that is contained in the
ID3 tag. If the song name is not
present in the ID3 tag, then the
radio displays the file name without
the extension (such as .mp3) as the
track name.
