This link should be the post entered by "laxman310", which describes the process very well without purchasing any additional equipment. It's just a matter of clipping a couple wires and grounding an end (once you get the nav system out).
The reason I'm posting is that the wire harness described was a different one on my 2002 (I believe his was a 2004). The wire colors were perfect, just a different set of wires. I've attached a pic, pointing to the right one for me. Took a leap of faith, and it worked like a champ - 15 minutes.
