Took me a while to figure out downloads were not intuitive to me. Finally found my problem in FAQ (How do I find my serial # and content ID). When I added my unit to my account, I had no clue what content id was so I just put something in there. could not get any detail on map. Thanks to the FAQ, problem solved and map loaded right away. Now when I see some good weather, I will check it out and try to add some more contours.
