Summary: The Magellan RoadMate 1700 isn't a GPS device for everyone, but with its huge screen and road-trip-friendly features, we think truckers and RV drivers will love it.
Pros: The Magellan RoadMate's OneTouch menu puts the most commonly accessed destinations and searches at your fingertips at all times. The smartly designed destination confirmation screen gives you a good deal of flexibility as to how they get where they're going. Its large 7-inch touch screen gives you more real estate for maps and menus.
Cons: In urban environments, the 1700 takes longer to establish satellite lock and can be inaccurate. Its 7-inch screen size may be too much for smaller dashboards and can make mounting it awkward. Its battery life is extremely short.
Excerpt: The Magellan RoadMate 1700 sports one of the largest screens available of any after-market navigation device — a whopping seven inches! Clearly aimed at truck and RV drivers, the 1700 also offers lane assist and multi-destination routing.
