I'm on a iphone 6 running 10.0.2 with all the same errors as previously mentioned by myself and others.
I decided to go Bluetooth and it works to no surprise minus CarPlay over USB. Streaming songs n making calls.
So i tried plugging in the phone to the CarPlay connect and it took it without an issue. Haven't received the common errors, made calls through CarPlay played and changed music through CarPlay.
I will keep you posted.
Ps. Enable always and access while locked are active
This was a flash in the pan. After work I expected the connection to work but no luck.
Connected Bluetooth first then played music then connected to CarPlay USB and back to square one, no device connected error.
Anyone know where to find this 10.1 Beta?
