Summary: The Garmin nuvi 52LM has a pretty big 5" screen and excellent technological features. Adding waypoints is easy; changing settings is easy. The "lane designator" at crazy Interstate exchanges is wonderful. There is a lot to like. I bought a refurbished unit and saved about 50% on the retail price. It works well, but the screen must have had a rough life before I got it. It is like someone rubbed the screen with steel-wool.
Summary: I'm from the uk but travel in the states on and off. I have the uk version of this device and it was cheaper to buy this than buy a U.S. map for that device. Works a treat, updated with the free map upgrade back in the uk when I got home so all ready for my next trip over the pond.
