My iPhone XR does not generate a list of "available cars" in Setting

I go to "Settings" then to "General" then to"CarPlay" then I see my Chevy "MyLink" which I have installed before, and works well, altho only with a USB connection (It's a 2017), and on the same screen, lower, I see "other cars" with a pinwheel that never stops. The owner's manual says I should see a list of models, and I should choose mine. I wonder if there is something wrong with my phone. ApplePay as been unreliable for a couple days.

It turned out that there was a problem with the software in the car. "We've seen this before, but once and it was 6 months ago." It was gratifying, since I had the time, to see my salesman, his supervisor, then two service people take on the problem with total confidence, and being puzzled, as I had been. To their great credit, they figured out that they had to update or somehow patch the software in the car, which took half an hour but worked, and the problem is solved. I want to be clear that I LOVE the car, am working to learn the menus, and that the dealership is superb, always willing to help me.
