Ask Siri (Almost) Anything
In the past, using Siri on CarPlay was sometimes annoying, because the whole screen suddenly became Siri, blocking out everything else. Whoever came up with that idea did not think things through. Fortunately, Siri has now been updated to an unobtrusive little line at the bottom of your dashboard screen, making it far, far easier to ask her questions about weather, traffic, nearby restaurants, and so on without blocking everything else out.
On the subject of blocking things out, a related problem with CarPlay was how it would instantly shoot back to the home screen if you tried to access an app on your iPhone that didn’t work with CarPlay. That’s now been changed, too, and CarPlay will keep cool if someone starts to open up other apps on your phone (like the Music app, which will no longer take over your directions on the CarPlay screen).
