CarPlay is a great idea, I'm having my first proper day with it today and I'm about to go out to the car and mess around a bit more. But third party apps like spotify, audible, etc are crap. Very buggy at the moment. Sometimes tracks play, sometimes they don't. It's a problem with apple or the third party company (spotify,etc). So far, I'm a little disappointed with CarPlay, as I wanted my spotify integrated into my car.
