Thanks, Strmwalker, for the video. I saw the part where he moved the cursor around on the map and maybe that is all it will do. So, I went back and found the video I was watching before and I was wrong about it being a Humminbird. It's a Garmin, but not the one I have. His Garmin has lake maps on it, and he probably paid way more for his than I did for mine. Here is a link to the video I was watching.

Now I know the maps will be different because the Striker doesn't have anything nearly that sophisticated, but the question is, "Can I put a cursor on a down view image or a side view image and mark a waypoint like this fellow did in the video?
Thanks
