I haven't used it for geocaching yet, but it has all the same functions, namely off road routing with directional arrow) that the GPS V has so it shouldn't be any different... just faster. Hrm. Your right about the price. I thought I'd paid $400 for it but turns out it was $480. I must have blocked that out. Heh. Is that $250 WITH the mapsource data?
Still, the speed and memory are well worth the extra bones IMHO. I could be surfing with 56k but for twice the price I'll take DSL anyday. Not apples to apples but you get the drift. The speed and lack of memory on my V used to drive me NUTS.
