I have the 2013 Fusion and iPhone 7. I upgrade to the latest version of SYNC with MyFord (NOT MyFord Touch), and the Siri functionality was broken in this release. It makes it a bit of a pain as siri used to just come right through the speakers before but now, I have to mess with iphone settings in order to get siri to work... which saves me from interacting with my phone while driving.
Anybody else have this issue? I was told by the Sync team at Ford that this was intended but I would love to roll back if possible.
