I have a Simrad chart plotter that takes the C-Map chip, I believe they call it a C Card not an SD card. The only way I can log any way points is when I am in the boat. Does anyone know of any hardware that I can hook up to my PC, insert the card, and log GPS locations and or plot a trip on my PC then insert the card into my chart plotter before a trip and have it all right there?????? I have searched but may not be typing the right search criteria. I did not buy this new, so owners manual is no help.
