Think this is something with my Garmin. When I got it I had to download some file to computer, so the computer would talk to the Nuvi. You could use that file or use a wireless type program. Can't remember what it was, but I had a computer problem and lost that file. Streets & Trips 2011 will let me send Data "trip.gpx" file to the Nuvi, but the Nuvi does not seem to receive it. Like I said, it worked with the S&T2010.
