TomTom has built its reputation largely on creating super simple and easy to use in-car GPS receivers. The XL 350-TM is the "lifetime traffic and maps" version of TomTom’s 350 line and comes with an extra $30 on the price tag. With this version, you'll be able to keep your GPS up to date with the latest map and traffic data for as long as you own it; a worthwhile investment assuming you connect your GPS to your computer every once in a while to take advantage of these benefits.
