Magellan is using SEMA 2007 to launch the latest portable navigation system in its RoadMate family. The RoadMate 1200 is a "budget-conscious" pocket-size GPS device that replaces the RoadMate 2000 at the bottom of the Magellan lineup. The RoadMate 1200 comes with a suggested retail price of $229 and features a 3.5-inch QVGA touch-screen display and a Centrality Atlas processor, which Magellan says provides "superior GPS performance and navigation." Based on our initial attempts to program a destination using the model on display here at SEMA, we're not too convinced that the processor works as advertised, as the device took a good 20 seconds to suggest a route and then locked up on us. But it may have been a preproduction model, and we'll reserve judgment until we get one in for a full review in the next few weeks.
