When creating an MP3/WMA disc:

- 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.

- Make sure the CD does not have more than a maximum of 50 folders and playlists, and 255 files to read and play.

- 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. Keep the total number of folders to a minimum to reduce the complexity and confusion during playback.

- Create playlists that have a .m3u or .wpl extension; other file extensions may not work.

- Minimize the length of the file, folder, or playlist names. Long file, folder, or playlist names, or a combination of a large number of files, folders, or playlists can cause the player to be unable to play up to the maximum number of files, folders, playlists, or sessions.

- Finalize the audio disc before burning it. Adding music to an existing disc can cause the disc not to function.

Playlists can be selected by using the previous and next folder buttons, the SEEK arrows, or the FWD or REV buttons.

An MP3/WMA CD-R or CD-RW that was recorded using no file folders can also be played. If a CD-R or CD-RW contains more than the maximum of 50 folders and playlists, and 255 files, the player lets you access and navigate up to the maximum, but all items over the maximum are not accessible.

The HDD Radio can support more than 255 files on an MP3/WMA disc.

The HDD Radio does not support playlists on a disc or USB storage device.
