This guy did conversion a while ago. It seems to be a lot of work but it is possible. YOu can get navi unit from ebay or junkyard. Dealer will charge way too much you as might as well trade in for Navi

 

I did the conversion. Here is the thread that I started. It may answer some of your questions.
