The Sync 3 update from 1.0 to 2.2 has just been released. If you have a Sync 3 system that doesn't have Apple Carplay or Android Auto this is the update for you! Of course for Apple Carplay you still need the upgraded USB hub but at least we have the official update now. You should be able to find the files, and if your car is eligible for the update here: https://owner.ford.com
I've heard that it isn't yet working for 2017 Models with the Sync 3 2.0 system, so YMMV if you own one of those.
