What cooks my god damn goose isn’t the stupid screen I’m going to break one day. It’s that they run buses for other systems through the radio so you can’t replace it with what you want.
Yep, infotainment and HVAC should have different control systems entirely. If your radio dies it should not mean the death of your car completely. And I consider not having access to your government mandated cameras and defrosters a dead vehicle.
