Have you used PCM much? In my opinion it is terrible until PCM 3.0, and even then it isn't very good. I would go with a good aftermarket navigation unit long before I wasted my time installing a PCM unit.

I haven't messed with PCM much, mostly only in loaner cars, but I have a couple year old Pioneer and it works very well in the car. Much better than the factory unit would have with more and better features than any factory unit would have had.
