Pioneer is listed as one of the partners in the open automotive alliance. As is alpine, and every other major aftermarket head unit maker. 

I would not be surprised if the NEX has a future software update that will enable this. 

The biggest problem is that CANBus protocols are mostly-closed; this is much-more of an issue than just entertainment, and IMO it's unacceptable.

Tied sales are supposed to be illegal unless the "tied" service is FREE for the life of the product.  That's the law, and yet automakers manage to skirt the requirements (they "technically" get around it.)  It would be nice if we had a choice but ALL of the automakers do this, which means there is no market force to change it available.

I'm not normally one to back government intervention but there's a reason the Sherman and Clayton Acts were passed in the US.....

First time I've seen Spotify on the Carplay screen.

https://www.apple.com/ios/carplay/ its been one of the supported apps for carplay since the begining. It was one of the original 5 with MLB being added after WWDC.
