Just don't connect smart TVs to the internet. Get something cheap like a raspberry pi + wireless mouse/keyboard or an android TV box for the same functionality. (More functionality, actually)

My '21 Malibu had it out of the box. I can't speak for Car Play, but wireless Android Auto is 95% flawless. There's that 5% where I get in and the phone won't connect automatically. But I think it's an issue on the phone side. I have to unlock the phone then it kicks in.
