Never Ask for Directions Again

Sick of dead ends? We tested free mapping sites and in-car GPS gadgets to pinpoint the ones that won't steer you wrong.

Two hundred years ago, when Meriwether Lewis and William Clark began their famed expedition, maps labeled much of the western United States as terra incognita--unknown territory. For today's traveler, terra incognita can be the next state, the next town, even the next neighborhood. But unlike Lewis and Clark, we have a wealth of tools not only to help us get where we're going but to find services--fuel, shelter, and the all-important latte--along the way.

For this review, I looked at four free Web-based mapping tools and five portable GPS navigation devices costing $460 to $600, all of which provide descriptive and graphical guidance in real time. I also tried two PC software packages that offer comprehensive mapping and trip-planning features. These services and products may not always reflect the most recent road changes, but hey--your old paper maps will never update themselves.
