I avoid Apple like the plague but even that overpriced status symbol should have an "airplane" mode that may or may NOT disable bluetooth. Otherwise, it's always connected to Apple, NSA, China,...IPhone 12
Not plugged in. Thinking in these new covid phones off doesn’t mean off
SInce you cannot take the battery out anymore, putting it in an enclosure that is impenetrable to radio frequencies is the only way to have it reliably off. Or put a bullet through it.
My guess is being that old, the new phone sees the car system as just a bluetooth headphone so it connects the same it would on the airplane
The AI is too smart, but at the same time just treats the older radio like a simple device
