I went down and bought one of those paper maps to test it against my Nuvi 350. Had my girlfriend hold it up so I could follow my route on the map as I drove. Worked pretty good although she did miss annoucing so of turns and when I made a wrong turn it took forever for her to recalculate. She got kind of ticked when I asked her to use the map to find us the nearest hotel. She couldn't do it. I told her my Nuvi could. She then proceeded to tell me what my Nuvi couldn't do. I'm going to send flowers today and hope for the best.
