Then you haven’t used it. Topping the list of improvements for me is the fact that my passenger can now use my phone without affecting CarPlay. For example, using phone to browse Spotify will no longer take Maps off the screen.If it's not broke, why fix it?????
I don't see anything that has been added into 13 that makes CarPlay any better.
Calendar integration is very useful for those of us who take conference calls while commuting.
Siri not taking up the whole screen is great.
Album art is nice.
