Using an MP3
Format
Radios that have the capability of playing MP3’s can
play .mp3 or .wma files that were recorded onto a
CD-R or CD-RW disc. Radios that have a USB port
can play .mp3 and .wma files that are stored on a USB
storage device as well as AAC files that are stored on
an iPod
®.
Compressed Audio
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.
USB Supported File and Folder Structure
The radio supports:
•Up to 700 folders.
•Up to 8 folders in depth.
•Up to 65,535 files.
•Folder and file names up to 64 bytes.
•Files with an .mp3 or .wma file extension.
•AAC files stored on an iPod.
•FAT16
•FAT32
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
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.
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 four 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.
Preprogrammed Playlists
CDs that have preprogrammed 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.
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.

The range of the Bluetooth system can be up to 9.1 m
(30 ft). Not all phones support all functions, and not all
phones are guaranteed to work with the in-vehicle
Bluetooth system. See www.gm.com/bluetooth for
more information on compatible phones.
Voice Recognition
The Bluetooth system uses voice recognition to interpret
voice commands to dial phone numbers and name tags.
Noise: Keep interior noise levels to a minimum.
The system may not recognize voice commands if
there is too much background noise.
When to Speak: A short tone sounds after the system
responds indicating when it is waiting for a voice
command. Wait until the tone and then speak.
How to Speak: Speak clearly in a calm and natural
voice.
Audio System
When using the in-vehicle Bluetooth system, sound
comes through the vehicle’s front audio system speakers
and overrides the audio system. Use the audio system
volume knob, during a call, to change the volume level.
The adjusted volume level remains in memory for later
calls. To prevent missed calls, a minimum volume level
is used if the volume is turned down too low.
