What would need to happen is you'd plug in your phone and the phone screen should show on the car screen. It would be similar to plugging in your laptop or desktop to a larger monitor and show the display.
I don't think that technology is available yet to even plug your phone into a computer screen. Once that comes out though I'm sure it will be a short time before it integrates to a vehicle.
FYI I'm sure they have some sort of cheap Chinese version of it. Google it
