Yes, the entertainment system is different from the system that runs the car, but there is some level of communication between the two. I think you've just identified the root cause of at least one set of problems. The essential control systems in a vehicle should ideally be separated from other vehicle functions to prevent interference, whether accidental or deliberate, from compromising vehicle safety. The approach now being taken by manufacturers with their always-online, increasingly automated cars may be undermining that separation, without necessarily having adequate safeguards in place to ensure safety and reliability are maintained.
