Using an MP3 CD and DVD
MP3 Format
There are guidelines that must be met, when creating an
MP3 disc. If the guidelines are not met when recording a
CD-R(W), the CD may not play. The guidelines are:
•
Sampling rate: 8 kHz, 16 kHz, 22.05 kHz, 24 kHz,
32 kHz, 44.1 kHz, and 48 kHz.
•
Bit rates supported: 8, 16, 24, 32, 40, 48, 56, 64, 80,
96, 112, 128, 144, 160, 192, 224, 256, and 320 kbps.
•
ID3 tag information is displayed by the radio if it is
available. The radio will display a filename, song
name, artist name, album name, and directory name.
•
Maximum number of folders is 255 with a maximum
hierarchy of eight folders.
•
Create a folder structure that makes it easy to find
songs while driving. Each folder or album should
contain 18 songs or less.
•
It is recommended that there is a maximum of
1024 files on a disc.
•
The files can be recorded on a CD-R or CD-RW
with a maximum capacity of 700 MB.
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 DISC. All files contained directly
under the root directory will be accessed prior to
any root directory folders. However, playlists will always
be accessed before root folders or files.
Empty Directory or Folder
If a root directory or a folder exists somewhere in the
file structure that contains only folders/subfolders and no
compressed files directly beneath them, the player will
advance to the next folder in the file structure that
contains compressed audio files and the empty folder
will not be displayed or numbered.
No Folder
When the CD contains only compressed files, the files will
be located under the root folder. The next and previous
folder functions will have no function on a CD that was
recorded without folders or playlists. When displaying the
name of the folder the radio will display DISC.
When the CD contains only playlists and compressed
audio files, but no folders, all files will be located under
the root folder. The left and right arrow buttons will
search playlists (Px) first and then go to the root folder.
When the radio displays the name of the folder the
radio will display DISC.
