I think there are pretty good ways to do it from computer if your files are labeled correctly. I load some of mine by hand, tho....If you open a lakemaster or navionics on your unit, then activate the cursor and put the cursor on the lat/long numbers. Then just click mark on unit. Might even be able to do it without the GPS card, because the cursor will show lat/long regardless of mapping, I think
