Re: Carplay, my wifes car is an '18 Explorer. I've upgrade the from Sync3.0 to Sync3.4 - both versions of it had carplay work flawlessly (granted not wireless, but even the if I delete wireless setup and deny wireless when re-setting up it still crashes).
Even better feature of the ford - when a text comes in, it doesn't flash to the Carplay to show the notifcation, it's able to do it over the Sync UI. And when on the Carplay UI, adjusting something via buttons will just have the Sync Notification over the Carplay UI. None of this switching screens back and forth.
Uconnect compared to Sync - Sync has it beat easily.
