Query: Garmin Nuvi 350 GPS

My first GPS purchase. Find very easy to use, especially voice prompts, which allow you to keep your eyes on the road. A worthwhile product that saves time by avoiding pulling over to read a map. Recalculates route if you miss a turn - very convenient. Never get lost again! Like the portability and pedestrian setting so you can walk around the big city and find attractions quickly.
