Apple has not officially announced wireless for Carplay, although it is likely that they are working on it. Note, though, that it will require a Wifi radio in the car/headunit, since Bluetooth does not have enough bandwidth to mirror the display.no, not a requirement. apple announced both wired and wireless protocols, but most manus are rolling out wired-only right now, for reasons I'm not aware of.
That may be so, but you're not supposed to use any GUI while driving. Even if Carplay is somewhat simplified, it is still a distraction.its not about the screen size, it's about UI and integration. CarPlay is better suited for auto use than normal iOS.
Not sure what you mean. I can control phone calls using the steering wheel controls via Bluetooth, and even trigger Siri with the phone button. Not sure why I would want to integrate Carplay with the reverse camera? That comes on automatically on the integrated screen when I'm in reverse.also, you can't integrate your phone into your car's steering wheel controls or car cameras -- head units can.
It's not possible to connect the iPhone to an external GPS antenna.if you plan on using the GPS you'll want to plug it in anyway, because: 1) external GPS antenna, and 2) battery charging while GPS is draining it.
At this point, I think Carplay is pretty much a dud, unfortunately.
