Garmin's City Navigator is like having a front seat co-pilot who's awake and actually paying attention for once—in fact, it's a lot better than that. Whether you're traveling in a new state or unraveling tangled back-country roads in the hills of your hometown, you have an immensely detailed road map every step of the way. Certain compatible Garmin devices give you turn-by-turn navigation and audible directions to keep you on route without having to stop and scratch your head trying to read the bleeding ink from your homemade napkin directions. No back-tracking required. With 10 million points of interest, there are virtually endless options for fueling up, finding a hotel if you're on a tour, or even navigating back to the airport after a travel race.
