Specifically designed with Joe the Plumber in mind, the iTrack is easier to use than a cell phone and cheaper to operate than most GPS services on the market. There aren't any "special" codes to memorize and you won't need to take any college-level computer courses to learn how to use it. If you can use Google or Yahoo maps, you'll find where your iTrack is - quickly and accurately. Product Review!
