Reviews of Cobra CPSM 3000, Garmin C320 StreetPilot, Lowrance iWay 500C, Magellan RoadMate 760, TomTom Go 300
Over at Slate there is a review comparing the Cobra GPSM 3000 Nav One Mobile Navigation System, the Garmin c320 StreetPilot, the Lowrance iWAY 500C, the Magellan RoadMate 760, and the TomTom Go 300.
None of these systems stands apart for its accuracy. All of them are equally amazing at pinpointing your location, and all of them give directions that are as good as any online mapping service. A few of the directions I received—like the GO’s command to drive from Georgetown to Adams Morgan via Q Street—were inspired. But if you spend your days driving around the same suburb or city center, none of these units will make your life much easier—you’ll be better off planning your occasional trips into unfamiliar terrain with a road atlas or MapQuest. The StreetPilot and the GO were my favorites by far. They’re both small, easy to set up, and will inspire gadget lust in all your friends. How to choose? Not even the shape of the receiver helps—they look nearly identical.
