TomTom One 3rd Edition

The TomTom One 3rd Edition has traditionally been the least expensive auto GPS unit recommended in reviews, but newer models are now available that are nearly as cheap. The One 3rd Edition cuts costs by omitting several common features: Bluetooth hands-free calling, a widescreen display and the ability to speak street names. Although some testers say the One 3rd Edition does a fine job navigating, others find that TomTom GPS units -- which use Tele Atlas mapping data -- never navigate as efficiently as units from Magellan or Garmin, which use Navteq data. The One 3rd Edition does offer some TomTom-specific benefits, such as celebrity voices (like Gary Busey and Mr. T) for the spoken directions.

ConsumerReports.org does the best comparison testing of the TomTom One 3rd Edition auto GPS, ranking it against dozens of other GPS units. Choice magazine in Australia and Consumer magazine in New Zealand conduct similar comparison testing, but they rate fewer units, and not all of them are available in the United States. Reviews at GPSReview.net and Kiplinger.com describe the One 3rd Edition's features, but they don't test the unit. We found a healthy number of owner-written reviews for the One 3rd Edition at Amazon.com.
