Car GPS (Navigation) comparison chart

In addition to being a solid navigator for the price, the Magellan RoadMate 5175T-LM Traveler also packs a few features to help users to plan vacations and explore attractions in unfamiliar cities.

Pioneer's AppRadio has great potential as a cost-effective way to add touch-screen iPhone app control to a car's dashboard, but interface and multitasking issues will prove frustrating for early adopters.

Garmin's formula for entry-level GPS devices doesn't change much with the new Nuvi 50, but small tweaks, a lower price, and a massive screen enhance value.

The JVC KW-NT3HDT stands apart from the competition, both with its impressive feature set that includes HD Radio and traffic data and its rare detachable faceplate. Despite a few hardware and software quirks, we think there's a lot to like about this unit.
