This marks a return to the days of massively overpriced AM radios. The problem now is the way these systems are physically molded into the car. Back in the day you could put a good radio in. Good luck with that now.
All we really needed for the last 15 years was a recess in every dashboard in which to put our already-giant phones, with a power and audio dock. I can't deny that CarPlay works relatively decently in my experience, but it's not really necessary.
Even worse is the removal of auxiliary jacks from car stereos, another huge regression. So people can't even get a Bluetooth adapter that plugs into it and supplant this GM nonsense.
There is no end to the mania for screwing the consumer. Subscription car features... WTF. Keep your old cars, people.
