Cables might change but the protocol is actually pretty simple. VW manages to support Carplay, Android and mirror link. What I can see changing over the years is the phones being able to stream data from the cars sensors, making things like Automatic a thing of the past. It would be really nice if my car could report gas mileage to my phone and the phone be able to do whatever with it.
