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.
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: (1 items) If you're looking for a portable GPS navigation device with a mammoth screen, Magellan's RoadMate 1700 could be just the thing. Measuring 7.5 by 4.2 by 0.6 inches and weighing in at a hefty 10.7 ounces, the 1700 is big enough to pack a gigantic 7-inch screen. Bigger is not always better, though.
Pros: Excellent POI handling with built-in AAA tour book, Large, bright 7-inch screen
Cons: No traffic receiver, Video input didn't work as expected
