With my 465t I can make a waypoint in Basecamp, connect my GPS. When it comes up all you have to do is copy waypoints/routes to the memory of the GPS directly not the memory card. Not necessary to upload.
I was surprised when I copied a route to my GPS. I knew it would copy the waypoints and the route but it copies it in the Catagories which are made up of the list. Nice supprise.
Now all I would like is to get a way to keep shaping points and not have them converted to waypoints. I don't need the distance to the shaping/waypoints just the destination.
