Using an MP3 (Radio with CD and Six-Disc CD Player) MP3/WMA CD-R or CD-RW Disc The radio plays MP3/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 are available for display by the radio when 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/WMA files are recorded on a CD-R or CD-RW disc. • Do not mix standard audio and MP3/WMA files on one disc. • The CD player is able to read and play a maximum of 50 folders, 15 playlists, and a combined total of 512 folders and 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. Compressed Audio The radio also plays discs that contain both uncompressed CD audio (.CDA files) and MP3/WMA files. By default the radio shows the MP3 label on the left side of the screen but plays 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 .mp3 or .wpl extension (other file extensions might not work). 3-104
