Thread: Mapping and waypoint question

I have lowrance fish finders and navionics map card, I want to view my map card with way points on my computer. Is there any software that will let me do that. I would like to mark spots on the map on the computer, and then load them into my lowrance.

I bet there are several ways to get this done. A registered Navionics card may have "rights" to bring maps up on PC, mark waypoints, and then put them on an SD card. And maybe Lowrance has something similar to Hummviewer?

Those with more knowledge will steer you right.
