Buy a cheap cell phone mount (I like the wireless charging vent clip variety), and use android auto. It will let you use it while in motion, gives traffic alerts and speed trap alerts (Google maps) and uses the factory nav screen and buttons.

Just finished the updates. Took about 15 minutes for the Sync update. My old version was Build 18093_PRODUCT. The new version is Build 19205_PRODUCT.
Chuck, this update was over 800MB compressed so I don't think they make it available via WiFi. I have a router in my garage and the vehicle connects regularly but this one did not come up. Had to log into the Ford owner site to see the alert.
The new maps are indeed out of date. The latest maps are apparently from the 1st quarter of 2018. The prior maps installed in the vehicle since I bought it new were from the 1st quarter of 2015.
