I have a helix 7 gps on the front of my boat and I am looking at a helix 10 for the console.

If I have a card in the helix 10 can I use it to transfer the waypoints and download them to the helix 7 fairly quick and easy? Or would I need to get 2 memory cards and transfer points from one card to the other?

Maybe there is an easier way.

Thanks for the help
