I personally have had the Verizon Navigator and thought it was really good.   However, as someone correctly stated . . . is it $10 bucks a month nice?    After the initial novelty of it kind of wore off, the answer became clear to me and I canceled it.   However, it's nice to know that you can re-activate it in a minute either monthly or just for a weekend if you're going on a trip or something.    Now if I seriously used a GPS often I too would invest in a dedicated unit in order to gain a larger real-estate screen which can be really helpful.
