My wife recently bought a 2017 Platinum Explorer with Sync3. My 2015 Expedition only has Sync with My Ford Touch. The Sync3 seems like a much more cool and functional platform. Particularly when interfacing with my iPhone. I found, when looking on the web, there are upgrade kits @ $1500-$2500. It seems like it should be more easily upgradeable. Has anyone made this upgrade? Any input is welcomed.
