Audio Systems: stereo compatability, eddie bauer, present system

Question
I have an 02 eddie bauer explorer and the stereo doesn't have mp3 or xm sirius capabilities. if i found a newer say 04 cd changer with those features would it fit and or harness be compatible?

Answer
Sorry, I am not sure and I am not where I can research it thoroughly.  

But, you can update your present system.  Just go to this URL and look down through the add-ons available for the 02 explorer.
