Well I downloaded the app and I am impressed. I tracked myself from home all the way to work (it will also give you altitude readings). You will of course need to be "hooked up" for tracking and such but if you just need a map (like the state maps you can get) it has virtually every road there is and it also shows a lot of land features, trains, bodies of water, state lines and will also show county lines if you want. And it's free so you could always download it (needs about 2gigs) and could delete it if you don't like it.
