Product Description, December 12, 2007
The main purpose of any car GPS device is to take you reliably from point A to B. Here the GPS-310 performs nicely indeed, providing several options for finding your destination. To get going you can select either a street address, a specific point of interest such as a gas station or restaurant, a recent or saved destination, a postal code, or an intersection (if you're not sure of the exact address). To speed up text entry, the unit employs an intelligent auto-completion feature that displays only the letters that spell an item in its database. This greatly reduces the letters from which you have to choose to tell it where you want to go. Once it knows where you are headed, the device offers you the choice of shortest distance or most use of freeways or other high-speed arterials. You'll also find a trip planner that lets you lay out and save multiple destinations, as well as avoidance choices for routing your trip away from borders, toll roads, unpaved roads, ferries, and more. If you take a wrong turn or need to use a detour, the GPS-310 will automatically re-route you and get you back on your way. And how did the GPS-310 perform out on the road? In a word, admirably. The responsiveness of the device and excellent user interface make it a joy to use. The GPS-310 also has an extremely fast and accurate GPS signal processor, so it locks, calculates and recalculates routes, and responds to commands quickly. One of the hardest things for a manufacturer without a long history in building GPS navigators is getting the routing algorithms correct, so it was nice to see that Harman Kardon seems to have gotten this right. In most cases, the device decided on logical and efficient routes, too--something that can't be said of all GPS devices out there.
