Can someone explain a particular aspect of wireless CarPlay that i cannot find anywhere. When operating in Wifi Direct at 5GHz, does it also operate 'normal' Wifi at 2.4 Ghz? And what about cellular data?
If I'm in my driveway and get connected, will my iPhone also connect to my home wifi for data, while connected via Wifi Direct to the head unit? Or when out on the road, will it connect to cellular data alongside Wifi Direct?
In either scenario the underlying question is the same. When seeing a 5GHz Wifi Direct connection, does the phone 'think' it is online via wifi - except that the head unit isn't actually an internet connection, resulting in a total loss of data because it doesn't connect to another wifi and doesn't connect to cellular data because it thinks it is connected to the internet through wifi.
I hope that all makes sense. I can't imagine Apple would screw this up. But i don't know enough about Wifi Direct to know if it can tell the phone this isn't really wifi in the normal sense, or if it is capable of dual connections to a router at 2.4GHz while also the head unit at 5GHz.

Wrong. I used to do this, and it worked for a while, and for many it still may work. Then one day I had problems and while on the phone with Apple they explained to me, and supported it with the fine print on their website, that Time Machine backups may only be made to a USB hard drive if it is connected to an AirPort Time Capsule, and not an AirPort Extreme. It seems odd. It also seems silly to only allow USB Hard Drive Time Machine backups through a device that already has a hard drive (the Time Capsule). But, that's the reality from Apple's perspective. Apple does not support Time Machine backups made to a USB Hard Drive connect to an AirPort Extreme.Time Machine backups can be made to a AirPort Time Capsule, or to a hard drive connected to the USB port on an AirPort Extreme.
EDIT TO ADD: Okay they fixed this for the 802.11ac version of the AirPort Extreme. You can attach a USB hard drive to that model for Time Machine backups. For all prior versions of the AirPort Extreme, what I said above is still accurate.
