Using An Mp3 Cd - GMC 2006 Envoy Owner's Manual

Using an MP3 CD

MP3 Format
If you burn your own MP3 disc on a personal computer:
•
Make sure the MP3 files are recorded on a
CD-R disc.
•
Do not mix standard audio and MP3 files on
one disc.
•
Make sure playlists have a.m3u or .wpl extension,
other file extensions may not work.
•
Files can be recorded with a variety of fixed or
variable bit rates. Song title, artist name, and album
will be available for display by the radio when
recorded using ID3 tags version 1 and 2.
•
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.
•
Make sure to finalize the disc when burning an MP3
disc, using multiple sessions. It is usually better to
burn the disc all at once.
3-90
The player will be able to read and play a maximum of
50 folders, 50 playlists, 10 sessions, and 255 files.
Long file names, folder names, or playlist names may
use more disc memory space than necessary. To
conserve space on the disc, minimize the length of the
file, folder or playlist names. You can also play an
MP3 CD that was recorded using no file folders. The
system can support up to 11 folders in depth, though,
keep the depth of the folders to a minimum in order
to keep down the complexity and confusion in trying to
locate a particular folder during playback. If a CD
contains more than the maximum of 50 folders,
50 playlists, 10 sessions, and 255 files the player will let
you access and navigate up to the maximum, but all
items over the maximum will be ignored.
Root Directory
The root directory will be treated as a folder. If the root
directory has compressed audio files, the directory
will be displayed as F1 ROOT. All files contained directly
under the root directory will be accessed prior to any
root directory folders. However, playlists (Px) will always
be accessed before root folders or files.
