Compressed Audio The radio will also play discs that contain both uncompressed CD audio (.CDA files) and MP3 files. By default the radio will show the MP3 label on the left side of the screen but will play both file formats in the order in which they were recorded to the disc. • 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 .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 and folders, or playlists may cause the player to be unable to play up to the maximum number of files, folders, playlists, or sessions. If you wish to play a large number of files, folders, playlists or sessions, minimize the length of the file, folder, or playlist name. Long names also take up more space on the display, potentially getting cut off. • Finalize the audio disc before you burn it. Trying to add music to an existing disc may cause the disc not to function in the player. MP3 Format If you burn your own MP3 disc on a personal computer: • Make sure the MP3 files are recorded on a CD-R or CD-RW disc. • Do not mix standard audio and MP3 files on one disc. • The CD player is able to read and play a maximum of 50 folders, 50 playlists, and 255 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. 302
