Installed. That was easy. Works SOOOO much better. I dont have A4 for navigation, but as the navigation was worthless before the update I don't feel much loss until it is installed. Everything now appears to work quickly, smoothly, and correctly.
My one complaint is why the car cant send data to ford when you come home, put in park, and it connects to yoru WiFi. Seems like that would be a good time to upload and car health data.
