I am replacing an old GP30 gps with a new GP39. Is there anyway that I can transfer all my saved waypoints and routes to the new unit without having to enter them one at a time?
I can successfully download all waypoints and routes to my Offshore Navigator software using a home made cable. I have been doing this for years as a way of backing up the data and transferring routes from my computer to my GPS.
