The best thing to happen to driving and navigating in an unknown place, especially one with a different language, ever. Most of these units talk to you (in English) and all have the most up-to-date map information available, making them more reliable than their printed equivalents. A must have for any traveler, particularly one who does not speak Portuguese. Spend more time recreating and less time navigating.
