I'm really not a fan of depending on GPS. Everybody I know who does, express similar problems. Like going to an unused entrance, or getting there by via a strange and complex route no local would every use. I think they have their place but I think, for the most part, I will stay with using S&T for pre-planning purposes and maps for on the road makes more sense. I prefer to have typed up directions from S&T that say simple things like "take exit 82 and go south on I-5" vs. listening to "turn left, turn right, blah, blah" works for me. But I would love to hear how your experience with TomTom sometime.
