When Garmin introduced the GTN700 and 600-series navigators nearly two years ago, buyers hoped for substantial improvements over the dominant but aging GNS530 and 430. The wish-list for the second-generation, all-in-one navigators included a more modern display and integrated charting—including airways. Skeptically, the market expected a touchscreen feature set. Garmin delivered all of the above, of course.
But are the improvements enough to satisfy the demands of buyers ready to put their 15-grand-plus on the shop counter for a single-box upgrade? Does the touchscreen create havoc in turbulence as many feared?
