Consumer Reports ranks best GPS units

November 2, 2010

To help out, Consumer Reports has ranked the best GPS units.

Consumer Reports tester Frank Spinelli has driven thousands of miles this year. He and his team have tested more than 100 portable GPS units, ranging in price from $90 to $450.

They come with lots of features like traffic info. It can show delays along your route. Many new models provide traffic information for free, although there are small ads that may pop up onscreen.

Then there's voice recognition, which is found on the most expensive GPS units. You can operate menus and enter an address hands-free by speaking a command.

"Our tests found that voice recognition doesn't work well enough to justify the cost," said Jeff Bartlett of Consumer Reports.

But text-to-speech is a low-cost feature worth having. Rather than simply hearing "turn left," you're given the street name as well.

Another good feature - reality view. It displays a 3D view of exits and intersections. And "lane assist" shows you the best lane to be in for an upcoming turn.

In the end, Consumer Reports recommends the TomTom One 140S. It costs around $170 with this optional receiver that allows you to get traffic information.

It's $100 by itself.

For $150 or less, Consumer Reports also recommends the Magellan Maestro 4350 and the TomTom XL 340 S Live. They're both $150.

Almost all of the new smart phones have GPS applications.

Consumer Report finds the navigation on some can work just as well as a traditional GPS unit, but the smaller screens can be tough to see and the smaller buttons harder to use.
