I just got my grubby little paws (OK, not so little) on a Nuvi 255W. It took me a while, but I've downloaded a bunch of caches onto it, and while driving around, I've had it go "BING" a few times (my wife doesn't mind me geocaching, but said that driving with me now is going to be a lot more interesting). I've already used it to get to a cache that was newly published and I got a FTF out of it (the Nuvi lead me to the parking lot, and I pulled out ol' yellow to get me the rest of the way there).
Anyways, my question is this: I've got some time off over the next few days and I want to go looking for a bunch of caches. Is there a way I can tell the Nuvi, "I want to go to points A, B, C, D, and E, map out my route" or do I just bring up the cache one at a time, say, "Guide me here" and when I find that one, say "Guide me to the next one?"
