Using an MP3 MP3/WMA CD-R or CD-RW Disc The radio plays MP3 and 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 can display when files are recorded using ID3 tags version 1 and 2. MP3/WMA Format If you burn your own MP3/WMA disc on a personal computer: • Make sure the MP3 files are recorded on a CD-R or CD-RW disc. • Make sure the CD does not have more than a maximum of 50 folders, 50 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 8 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). Compressed Audio The radio also plays discs that contain both standard uncompressed CD audio and MP3/WMA compressed audio files. By default the radio reads only the uncompressed audio and ignores the MP3/WMA files. Pressing the CAT (category) button toggles between compressed and uncompressed audio format. 257
