Just an update. With all the problems people have had updating Sync, I have left my 2017 non-nav alone until a couple of weeks ago. I finally bought a 64 gb thumb drive and decide to try downloading and installing the update a couple of weeks ago. The first time I tried I could not download the update to the thumb drive. But I tried again a few days later and it downloaded. I was then able to install it successfully. I am not one of the very tech-savvy people here, but it worked fine. One thing the instructions do not make real clear is that during the installation you are prompted to restart the car several times. Don't be fooled into thinking that the installation is finished, even though the instructions on the Ford website say that when the installation is finished, you need to turn off the car, wait a short time, then restart it. It is very clear when the installation is all done and it is time to remove the thumb drive. There are also lags when there does not appear to be anything happening, but be patient. In the end it installed successfully and I now have Waze as an integrated app, which is why I bothered with the update at all.
