I am having issues with the Gen 2 adapter and the app crashing when I start it. It was suggested that I upgrade to Automatic Pro, but it does not include drive score, fuel level, or even audio feedback. All three of those are why I like Automatic.
Sorry for the difficulties! The Automatic Pro adapter does not have all of the same features of the 2nd Gen adapter, but the fact that is has 3G capabilities allows us to create new features that weren't previously possible such as live tracking and location sharing.
