GMC 2008 Acadia - Manual (Page 246)

Using an MP3 (Radio with CD and
Six-Disc CD Player)
MP3/WMA CD-R or CD-RW Disc
The radio plays MP3/WMA files that were recorded on
a CD-R or CD-RW disc. The files can be recorded
with the following fixed bit rates: 32 kbps, 40 kbps,
56 kbps, 64 kbps, 80 kbps, 96 kbps, 112 kbps,
128 kbps, 160 kbps, 192 kbps, 224 kbps, 256 kbps,
and 320 kbps or a variable bit rate. Song title, artist
name, and album are available for display by the
radio when recorded using ID3 tags version 1 and 2.
Compressed Audio
The radio also plays discs that contain both
uncompressed CD audio (.CDA files) and MP3/WMA
files. By default the radio shows the MP3 label on
the left side of the screen but plays both file formats
in the order in which they were recorded to the disc.
MP3/WMA Format
If you burn your own MP3/WMA disc on a personal
computer:
• Make sure the MP3/WMA files are recorded on a
CD-R or CD-RW disc.
• Do not mix standard audio and MP3/WMA files on
one disc.
• The CD player is able to read and play a maximum
of 50 folders, 15 playlists, and a combined total of
512 folders and files.
• Create a folder structure that makes it easy to
find songs while driving. Organize songs by albums
using one folder for each album. Each folder or
album should contain 18 songs or less.
• Avoid subfolders. The system can support up to
eight subfolders deep, however, keep the total
number of folders to a minimum in order to reduce
the complexity and confusion in trying to locate
a particular folder during playback.
• Make sure playlists have a .mp3 or .wpl extension
(other file extensions might not work).
