There is an epidemic of problems with power button failure on the lower end 40 and 50 nuvi series. I have literally seen hampers full of them returned. I don't have anything to do with the company but I have seen a returns dock (not in Kansas or Texas) and somebody goofed in this frail design. You basically have a piece of plastic melded at two fine points to the body. It does not take much at all to detach it. Its a pretty decent low end gps otherwise. It can load maps lightening fast - 20 minutes, as opposed to Tomtom's leisurely 2 hours.
