The -current- version of Android Auto only works with a cable. Some day in the future an update may allow wireless but who knows.
Wireless charging in the car is a 'gimick'. Wireless charging is only HALF the speed of wired charging, and unless you are on a long trip, its not going to charge much. It may save some wear/tear on the USB port however.
Also, you can't use your phone when its wireless charging because you'd have to pick it up off the charger.
I use wireless charging at at home (at night) when not using the phone. I also have a pad at work when I'm sitting at my desk. But I have no interest in getting one for the car.
