2016 Mustang, Sync 3.0, Apple Carplay, and HU5T-14F014-AD USB Hub

Hello.

I did a quick search about that part number, and I found this thread → "USB Hubs Not Supported" message after installing new USB hub in console

Long story short: he was not able to activate CarPlay with that part number.
So if you can, try getting a refund and an old part number.
