I had the opportunity to use Carplay in a rental Chevy Mailbu (shiver) and it was literally the best part of the car, other than stop/start at traffic lights. It was better done than our Audi's for message integration.
I wish Tesla would implement it or if their 3rd party SDK actual comes to be, that someone would (not holding my breath cause why would anyone).
You don't have to use it if you don't want but honestly it works much better for somethings than the current Tesla UI. I hope I'm wrong but I don't see Tesla getting quite the level of integration that Carplay or Android Auto can and that's a shame.
My 2019 Chevy Volt has Chevy's latest system and it's CarPlay absolutely sucks. Take Tesla's setup any day. Oh and it sounds like crap too.
My 2018 Jeep Summit with uConnect CarPlay was flawless. But I still don't miss it that much. It sure sounded great too. But Chevy, what a freaken mess. Makes me wish I never bought car.
Chevy will connect to my wife's phone as a phone and my phone as Media. Or the Reverse. It's different every time.
It screws up the volume on the phone so I don't get notifications when I leave car. It's slow to connect on bluetooth or when plugged in.
Then sometimes the ports just say no CarPlay today on that port but later it will.
And don't get me started on their "myChevrolet" App (which gets 5 stars in the App Store, while Tesla's get's 4).
