A replacement APIM will fix the problem, but if your car is out of warranty that's an expensive solution. In my case, updating Sync 3 to the latest map data solved the problem (note: updating the OS to the latest version doesn't replace the map data). I noticed that sync worked fine while Android Auto was running. And since Android Auto disables the Sync navigation I guessed that the problem is due to corrupted map data. It was a $100 gamble that buying the latest map data would fix it, but it paid off. The system works perfectly now. Ford probably doesn't want to admit that this is the problem because they don't want to give the map data away for free, and don't want to admit that it's prone to corruption. Of course, there could be other reasons why Sync misbehaves. Before wasting $100 on the maps, make sure that Sync is responsive while running CarPlay or Android Auto. That should confirm that it's the maps.
