specifics
TomTom's XL 340 • S navigator gives you the big picture with a 4.3" widescreen touch display and text-to-speech voice prompts. The detailed maps of the entire United States, Puerto Rico, Canada, and much of Mexico offer easy-to-follow routes and access to 7 million points of interest. You can find fuel, lodging, food, camping, and other nearby attractions and services with just a few taps of the finger, and you can upload custom destinations for future reference. Stay on course
The XL 340 • S offers helpful features to get you to your destination without fuss. The text-to-speech voice prompts announce the actual street name at upcoming turns, so you'll hear "turn right on Main Street," instead of "take the next right." Advanced lane guidance directs you to the proper lane for upcoming maneuvers so you won't miss a turn. And TomTom's IQ Routes™ technology saves you time by finding the quickest route to your destination using actual average travel speeds rather than posted speed limits. If it sees that a shorter route to your destination is backed up, it'll automatically seek a better way there. Keep your maps up-to-date
TomTom's MapShare software lets you fix map inaccuracies on the spot, instead of waiting for the next update. You can edit speed limits, points of interest, street names and directions, and more right on your XL 340 • S. You can also report the error directly to TomTom online and choose to share the fix with other TomTom users. TomTom verifies all changes so you can import edits made by others to your navigator. Extras that enhance your journeys
The "Help Me!" feature provides one-touch information for nearby emergency services, including phone numbers for rapid response. TomTom's EasyPort™ mount folds away for convenient storage and transport between vehicles. Plan trips with TomTom's free HOME software suite, which also allows you to update your navigator, and contact other TomTom users. You can add an optional traffic-information receiver to the XL 340 • S for time-saving updates on congestion along your travel path.
