It doesnt get any easier than this...

I downloaded this, after plugging in my Montana GPS it took about 5 minutes to transfer the maps to the computer. After that I opened a group of about 50 waypoints, it placed them on an accurate map and I then used the View in Google Earth option. It placed all my points and notes on a google earth 3d image that I could then send to somebody else. It doesnt get any better than this. BTW, this all took me (from no app to sharing) about 25 minutes.
