So i have IOS10 Beta on my phone, and when i go to carplay settings it asks me if i want to enable Wifi (if it's turned off) and has some text that reads "if your car supports wireless carplay, press and hold the voice control button on your steering wheel to start CarPlay setup"
Just thought people would be pumped! Hopefully Alpine and Pioneer make wireless enabled devices soon. Though ill say i think i prefer wired setup... but still a nice option to have.
