Please help! I have a Garmin 74DV Chartplotter that has all my favorite offshore fishing spots. I want to transfer those waypoints into my laptop using Google Earth. I've followed all the instructions but had no success. I used a micro-chip, formatted it and inserted it into the chartplotter. Copied the data to the sd card. Fro there, opened Google Earth, went to tools>GPS>import. Nothing happened. I've tried this several times...still no luck. Sounds like a simple operation, but must be something I'm missing or not doing. Can someone please give me a hand here, it's getting pretty fustrating.
