At the end of the day...I am not sure the '16 components are worth spending the money on. I don't find any difference in movies, nav speed etc etc etc...
Car play is "ok"... I mean, I just use Bluetooth calling. I like the nav on the dash better than the Apple nav.
And knowing Apple. Before this CarPlay gets good, they will have 6 generations of Updates on phones and os systems and cables etc etc before it gets worthwhile...
If I did it again, I would keep my '15 hardware and just do the vim and nav unlock....
