Just like other GPS gizmos, MapQuest stores its data and maps on Secure Digital cards. The touch screen is bright so you won't have problems looking for directions even in dimly-lit places. At 4.5 by 3.6 inches (WH) and weighing 11 ounces, this gizmo is easy to pack and use. I like the voice directions (in 30 languages and 50 voices) because it gives me the exact location of places and things. I love it when the director speaks in German with its
bedroom voice mode.
