Summary: We've had a few of these over the years, and with a map update, still running fine. Although Garmin's map updates are the greatest or accurate most times, Im still missing roads that have been around for years, and these dont allow for any sort of corrections.
Summary: The Garmin nuvi 660 was a very expensive gift for my husband. It worked fine for about two years and then the battery went. You need to be an engineer to replace the battery. The cost for an authorized dealer to do that is about what it would cost to replace the gps.
