Dash Express

Reviewers have been eager to try out the Dash Express's unique features. GPS Tracklog, GPSReview.net, Business Week, the Orlando Sentinel and The Wall Street Journal all test the Dash Express. Their write-ups describe how well its innovative features perform in the real world, as well as how well the Dash simply navigates. They don't attempt to compare the Dash Express with any other GPS units, because no other GPS units offer the same features. Consumer Reports does rank the Dash Express against 41 other auto GPS units, but testers there concentrate mainly on how well the Dash navigates -- they don't pay as much attention to how well its Internet and traffic features work.

The Dash Express is the first GPS receiver to do two things: It allows users to surf the Internet, and it collects "hive mind" traffic data from other Dash Express units on the road. Experts say the Dash Express may revolutionize the industry, with the big brands scrambling to copy it. The Internet connection means users can search for any destination - no more relying on finite points-of-interest databases - and get automatic map and software updates. The crowd-sourced traffic data really works well, testers say, although it might not work as well in less populated areas where there are few Dash users. One major flaw: The Dash Express doesn't navigate as well as Garmin nuvi GPS models. User reviews are mixed, with negative reviews likewise criticizing the Dash's navigation. Also, reviews say the unit is bulky and heavy - not the type to fit in your pocket.
