BS. It is available on old MFT (pre-2015) and on Sync3. Update 3.8 kills it, original 2015 MY 3.7 did not have it from the beginning.
It is not dealership's issue, but Ford IVT to blame.
Moreover, I am aware that some pre-2015 MFT owners were able to get Travel Link back by downgrading their MFTs back to 3.6
So whatever Ford officials tell us regarding this matter is nothing but lies.
