CD/AUX (CD/Auxiliary): Press this button to play a CD while a portable audio device is playing. Press this button again and the system begins playing audio from the connected portable audio player. If a portable audio player is not connected, No Input Device Found displays. 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. Using an MP3 MP3 CD-R or CD-RW Disc The radio plays MP3 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. • 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. • 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. Compressed Audio The radio also plays discs that contain both uncompressed CD audio (.CDA files) and MP3 files. By default the radio reads only the uncompressed audio and ignore the MP3 files. Pressing the CAT button toggles between compressed and uncompressed audio format. • Make sure playlists have a .mp3 or .wpl extension (other file extensions might not work). 3-69
