I think you meant "Carplay"I too was drawn in to Air Play when choosing on a new vehicle, too bad the execution is far from most things I've become used to with Apple.
The Air Play on my 2016 GMC Canyon is buggy as hell, running IOS 9.2 on my iPhone 6. Issues with Pandora constantly, issues with the Maps App not being in night or day mode at the correct time (at night a white/tan map is less than ideal as is a dark map during the day), issues with it staying connected, recognizing Siri commands, understanding my Siri commands, etc etc etc.
Now, since it's a 3rd party implantation by GMC, GMC blames my iPhone, and Apple blames issues with GMC. Typical pass the buck while NOBODY is or can do anything about my issues. Just finding out what version software and possibly getting updates is frustrating to say the least. Again, GMC dealer says it's on the iOS side, Apple says it's an issue with GMC...
It's cool when it works, but I feel like I'm back on IOS 1.0 when it comes to being polished or truly ready for prime time.
It's slightly better than using bluetooth though, which wants to play random music loudly everytime it connects, or returns from a call, etc. CONSTANT playing music when I want nothing of the sort. I don't have BT paired anymore so at least I can actually control what gets playing through AirPlay... most of the time.
This sucks. I wonder if it is a software or hardware issue. I haven't had much experience with Carplay since my I installed it in my wife's 2015 Mazda5, but the few times I used it, it seemed to work fine.
I wonder if it is an issue with Carplay, or iOS 9.
