PROS "Portable" and "big-screen" may seem contradictory, but TomTom has pulled it off with the XL, whose main selling point is its clear and bright 4.3-inch high-resolution display. The turn-by-turn voice instructions get louder as you accelerate, and traffic conditions can be beamed to the Bluetooth-equipped unit via your mobile phone.
CONS TomTom's software needs some work. Its main menu has too many choices to show all at once, so you have to take your eyes off the road to page back and forth. Similarly, should-be-simple tasks like finding the nearest ATM or parking lot take half a dozen taps on the screen.
BUY THIS ONE IF ... The demands of middle age require a supersize screen.
