Wow I shouldve read the reviews

I usually dont do this, but this app is soo terrible. wow.
Just garbage. Im even on stable 6.13 and this garbage crashes every time.
For once I legitimately want a refund for an app.
(Update:
Im now on the latest 7.0.4 (or something) and on an iPhone 5S, previously used a 4S) the experience is the exact the same. Awful. Seriously the worst I have ever had an interest in. I was on my way to purchase a Pioneer in dash player specifically for this feature and Im so glad I wasted the 4$ instead of 400$.
Just take it off the App Store.
