Although small in size, the screen is crystal-clear with amazingly sharp pictures. It comes with 32MB RAM and a fast 300 MHz CPU.

Voice Instructions

What Customers Are Saying

Customers describe the Tomtom ONE 3rd Edition as intuitive, easy to use, and reliable. It’s small and compact and will fit in your purse or backpack when not in use. The TomTom GPS is also easy to customize. One of its best features is MapShare which allows TomTom users to make map corrections.
