Softkeys
The six softkeys below the radio
display are used to control functions
that display as tabs.
The softkeys below the radio display
control the following features.
RDM (Random): Tracks can be
listened to in random, rather than
sequential order.
To use random:
1. Press the softkey below the
RDM tab until Random Current
Disc displays.
2. Press the softkey again to turn
off random play.
MP3 Supported Files
The Radio with CD (MP3) has the
capability of playing an MP3 CD-R
or CD-RW disc.
The radio can also play discs that
contain both uncompressed CD
audio and MP3 files. When a disc
contains both types of audio, the CD
player reads all MP3 files first, then
the uncompressed CD audio files.
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 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 disc display as
F1 ROOT.

Infotainment System
Empty Folder
Folders that do not contain files are
skipped, and the player advances to
the next folder that contains files.
File 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 file extension as the track name.
Track names longer than
32 characters or 4 pages are
shortened. The display does not
show parts of words on the last
page of text and the extension of
the filename is not displayed.
Playlists
Discs that have playlists that
were created using WinAmp ,
MusicMatch , or Real Jukebox
software can be accessed; however,
there is no playlist editing capability
using the radio. These playlists are
treated as special folders containing
compressed audio song files.
