Google maps is limited to a certain area being downloaded. It's OK for short distances or trips within a city. NOT OK for traveling on a straight road two states away. For offline maps/daily driving you need a dedicated GPS. Garmins are solid units and you can pick them up for <$20 used on eBay. Add a 2GB SD card to it and you can put a small map on it for the area you drive in. Magellan have crap hardware, but you can pop in an SD card and boot iGo Primo. Both have maps available online.
