Why does the owner’s manual say my stereo has DSP (Digital Signal Processing) and ASL (Automatic Sound Levelizer)?

DSP/ASL are not included in the base stereo or the premium stereo for 2004-5. DSP is not inclused in the 2006, but ASL is.  The Owner’s Manual is incorrect.

Does the CD player play MP3 CDs?

No, only CD Audio for 2004-5. It does support CD-Text, though, so you will get titles on supported discs (including ones you burn yourself if titles are added via Nero or other CD-Text capable burning software). 2006 supports MP3 CDs, but not playlists, and plays the songs in alphanumeric order, so you should probably rename the songs in the directories with 01-, 02-, etc at the beginning of the song names to get them in the original album order.
