No, until yesterday, there was no communication between my computer and my GPSR. When I say I downloaded something, I meant into my computer. My husband spent some time again yesterday with it, doing all sorts of things which I can't tell you what they are, nor probably does he specifically remember which did the trick, but now my MapSource and GRSr can communicate. We've been working on this off and on for over a month. I still can't get EasyGPS to work. Since I knew fundamentally the problem was in communication, I have not downloaded any other things to help with waypoints. I will now have to fiddle some more and see what I can learn.
Additionally, it seems I still can't get it to talk to MapSource on my computer w/ XP. the above was on my husband's computer using Win '98. Anyone else having problems they attribute to XP?
