Engadget - It's been a long while since Magellan comprehensively updated its RoadMate GPS mapping units, so the company's making up for lost time in style by introducing no less than seven new models in one shot. The RoadMate 2210, 2210T, 2220-LM, 2230T-LM, 5220-LM, 5230T-LM (pictured) and 5235T-LM all bring in a new Landmark Guidance option to give directions based on landmarks, not just those occasionally impenetrable street numbers.
