I'm inexperienced, old, and completely lost. I have a windows desktop and a 65. I've loaded express and basecamp on the desktop. I've loaded gpx routes to base camp and have copied those files to the external memory on my 65. These routes are in Arkansas and I am in Missouri. When I'm connected to my desktop, I can see all the routes. When I'm disconnected, I can't see them when I scroll the map to where they should be. Someone please help! I leave for a backwoods motorcycle event in a little over a week and need the routes.
