Enjoy the view: GPS with wide-screen displays

Bonnie Cha, Senior Associate Editor June 6, 2008

One of the great things about in-car GPS devices is that they give you both visual and audio navigation prompts to help you get to your destination. That said, the view isn't always that great when you're squinting to check out maps and text-based instructions on a small screen. To date, most portable navigation systems have been equipped with 3.5-inch touch screens, which has worked so far but is obviously not ideal. To be fair, GPS manufacturers are a bit restricted in what they can do, since they still have to keep the devices compact and portable. Yet, companies are now starting to churn out systems with slightly larger screens, usually in the 4- to 4.3-inch range (hey, every little bit helps, right?) and some even up to 5 inches. Here are six such systems. And remember, in addition to screen size, you'll also want to make sure that the displays offer good color output, sharp resolution, and readability in various lighting conditions.
