I've had a nüvi 1350T for 4 years and have just bought a nüvi 2797LMT to replace it. I have about 400 waypoints in my 1350 that I want to transfer into the 2797 via Basecamp. Using Mapsource, I attempted to create a current.gpx file to copy over the same file in the 2797's GPX folder, thinking that the waypoints would be accessible in the 2797. I fired it up and found them nowhere.
I know there must be a way to load them onto the new unit and then access them as desired, but ... how? I don't yet have a microSD card in the unit. Is this part of the problem?
