I am curious to see what people think of this program? Is it worth upgrading? I used it to lay out a nice route, however my shitty 590 garmin did not take to the uploaded file for anything. I fault the garmin for that. I was looking into trying to use my smartphone and Rever to help with turn by turn navigation. Under little review of the app, I am not sure you can get turn by turn navigation with it or not.
