If you are going to do nav you DO NOT want the factory system. First off, you cant use it since your car is pre- MOST bus (the fiber optic based system) and secondly the factory nav is horrible and ridiculously expensive compared to good aftermarket (which pretty much means Eclipse).
I would pick up either the Eclplise AVN5500 or the new (as in coming out any day now) AVN5510. AVN5500s now are down to almost $1000. The Eclipse software and mapping offers and amazing nav experience and is leaps and bounds ahead of everything else out there.
If you're going to do nav the only thing I'd consider would be an AVN (I have the 5500 and had the 5435 in a previous car)
