• MP3 folder mode represents a folder
structure consisting of one level of
folders. The CD player numbers all MP3
tracks on the disc (noted by the .mp3
file extension) and all folders
containing MP3 files, from F001
(folder) T001 (track) to F253 T255.
• Creating discs with only one level of
folders helps with navigation through
the disc files.

Audio System
If you are burning your own MP3 discs, it is
important to understand how the system
reads the structures you create. While
various files may be present, (files with
extensions other than mp3), only files with
the .mp3 extension are played; other files
are ignored by the system. This enables
you to use the same MP3 disc for a variety
of tasks on your work computer, home
computer and your in-vehicle system.
In track mode, the system displays and
plays the structure as if it were only one
level deep (all .mp3 files play, regardless
of being in a specific folder). In folder
mode, the system only plays the .mp3 files
in the current folder.
