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.


What are the 6 speakers in the base stereo?

They are:

  1. Front driver's tweeter (top front corner of front door) - 3.8 cm (1.5") 4ohm
  2. Front driver's full range (bottom front corner of front door) - 16 cm (6.3") 4ohm
  3. Front passenger tweeter (top front corner of front door) - 3.8 cm (1.5") 4ohm
  4. Front passenger full range (bottom front corner of front door) - 16 cm (6.3") 4ohm
