The thing that makes Sync 3 most attractive to me is the use of Android Auto/Apple Carplay. With those features alone, you never have to worry about mapping issues being outdated because you can utilize your phone's access to Google maps/Apple Maps.That makes sense about the options for the climate controls, etc.
Have you had the opportunity to check the maps as to how accurate they are? I was checking the website for updates for parents 2016 Escape. They still show it as having the latest version which I suspect now is out of date in some map areas.
