Car play issues

I'm having an interesting problem with car play. I can plug in fine and see the icons. when I call a phone number and then have to put in my password code to check my messages or when I am working with an automated system, it doesn't recognize the digits I am putting in. When I unplug it, it works fine. I have a 2019 Chevy Bolt and a 6s-iphone. The software is up to date.

Thanks in advance.
