iPhone 7 and my 2014 Volt

I searched the forum and couldn't find my specific problem, so I'll ask and see what happens.

I recently switched from a Motorola Droid Turbo to and iPhone 7. The new phone paired easily, but will not communicate with the car for text messages the way the android based Droid did. The car told me that my new phone will not work with car play.

So, is there an app for this? Seems like there's an app for everything!

Any ideas?

Thanks!
