Help! if any one is out there,,,,I've tried to install updates to my Nuvi 650 on six different occastions since June 2010 (firewall is off when I am installing updates). Now my Nuvi tells me there is no map data. Garmin sent me a disk to install but even this isn't working. I've reset the GPS,,,,to no aval. I've called Garmin; they have tried to install remotely. Does any one know what I'm talking about? Can I fix this problem? By-the-by,,,,I've updated my lil'GPS three times since I bought it from Garmin; I have know idea why its crapped out on me. Thanks.
