Thanks for that. I did download the upgrade file and have been hesitating to install it, concerned that it might do something to the car. I have the same make and model as you, except with nav. I was wondering if there was a particular file for mustangs or if it was universal to all sync 3 upgrades.
I don't believe ford will upgrade 2016s. If they haven't by now, they are probably not going to. So I will likely take a chance and do it myself.
