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.
When play enters a new folder, the
display does not automatically show
the new folder name unless the
folder mode has been chosen as
the default display. The new track
name displays.
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.
Track names longer than
32 characters or 4 pages are
shortened. Parts of words on the
last page of text and the extension
of the file name do not display.
Preprogrammed Playlists
Preprogrammed playlists that were
created using WinAmp ,
MusicMatch , or Real Jukebox
software can be accessed; however,
they cannot be edited using the
radio. These playlists are treated as
special folders containing
compressed audio song files.
Playlists that have an .m3u or .pls
file extension and are stored on a
USB device may be supported by
the radio with a USB port.
Playing an MP3 or WMA (in
Either the DVD or CD Slot)
If a disc is inserted into the top DVD
slot, the rear seat operator can turn
on the video screen and use the
remote control to navigate the CD
