A silly irritant perhaps, but I have a replacement Nuvi 3590. I tried to import the 290+ waypoints I had before I took my former 3590 swimming. The import appears on the "saved places" 3590 with a date x/x/2013. I would prefer to have the file name "waypoints" I've exported the file to my desktop as "waypoints.gpx. I am unable to ascertain how to import that specific file to the device.

Thanx for all the wonderful tips & assists I find here. You are invaluable!!!
