The nav and app system. It took a little work but I patiently called in weekly and did what the maker asked until it was resolved.
It's not your Sync system but another but the problem or bug was nation wide so while I did get an initial "you're the only one with this problem" the next week thousands more called in and they got to work on it.
So I agree it's a major pain but call Ford as high as you can to alert them to the issue.
Here I had a good experience once my dealer got past the "you're the only one" step.
I am an avid fan of CNET On Cars and Roadshow. Here is my story:
I bought a new 2016 Ford Expedition in late 2015. The truck is loaded and I love it. However the new Sync 3 system computer failed, and I had to take it into my local dealership to have it repaired under warranty. The dealership ordered the part, but told me it was backordered without a date. I contacted Ford Customer Care and their regional representative got involved and help to expedite the part to the dealership.
When the part arrived I returned with my Expedition and the dealership installed the part. When I got my truck back, I found they had installed the wrong part. It was clear that the Sync 3 system thought my Expedition was a C-Max hybrid. In addition, many of the controls and features in the car did not work. I notified the dealership, and contacted Ford Customer Care, and they re-ordered the part, which was backordered again. When asked, they could not tell me how they would confirm that the next part was the correct part.
As you can probably predict, they installed the wrong part again. Now, the first mistake is regrettable, but understandable as mistakes do happen. Repeating the mistake is (in my mind) in-excusable. As the customer, few details are shared with me, but what info I have been able to drag out of the dealership service advisor is that they have a catalogue problem. I am now in limbo, waiting for Ford to respond as to how they are going to proceed. From the time of the original part failure, it has been fully 8 weeks.
My question for you is: Do you have any suggestions as to how I can motivate them to actually fix my truck? The people I have interfaced with over email and phone are pleasant, but never resolve the issue. And after every communication I am asked to do a short survey to rate them. Well, of course I have no complaint with the way they are treating me, they seem genuinely interested in solving the problem, but they also appear completely impotent in their ability to do so.
Any help you can provide would be great!
