Summary: The TomTom XL 350 and XXL 550 series of GPS devices represent a marked improvement over the previous generation, keeping its great form factor while streamlining its software.
Pros: TomTom's interface has undergone a massive overhaul with this new series, resulting in a menu structure that's much easier to navigate. Trip routing happened quickly, and turn-by-turn directions were clear and concise. TomTom's EasyPort mount keeps the cradle with the GPS device at all times, which is great for portability.
Cons: Traffic service requires power cable be plugged in. Some menu options are oddly labeled. Lifetime traffic models occasionally overlays ads on the map screen.
