One of the pioneering companies in the Global Positioning System industry offers us the latest in its engineering efforts, the Garmin Navigation device. The Nuvi 3790T shows the focus of Garmin in updating and expanding from the technological perspective as well as design. Actually, we think they were just a little behind with their move toward the “ultra-thin” look that has appeared in so many hand-held electronic devices. Garmin did make a good move on this however because it is what the consumers wanted. Because the bells and whistles always seem to be improving, we ask ourselves, how much better can they get.
