Hah! Found this thread tonight while "updating" my Garmin Nuvi's with software and latest maps!
Since I got my Galaxy S III about 3 weeks ago, I have been looking at apps that would be useful for one of the things I like to do, which is to ride my moto. Looks like your app is the next one on my list, Dennis! I, too, saw the warning about the NEXRAD radar, so I will keep a watch on this thread as you update us on the progress of that. If I need to d'load the app for an upcoming long ride, I'll go ahead and do it and then provide feedback on how it worked for me.
