Here's the latest update from Ford. Z What's included in this update?
EA5T-14D544-AD SYNC2 - V3.8 Apple user's Posted Dec. 18, 2015: Some 2011 thru 2016 Ford vehicles with MyFord Touch and 3.8 software may have a symptom of Siri Eyes Free not working over Bluetooth properly with iPhones at iOS 9.2 software. Ford is currently working with Apple on a resolution for this. For the time being, having the phone plugged into the USB port allows Siri Eyes Free to operate properly. We recommend that owners of MyFord Touch-equipped vehicles have their phones plugged into the USB port to operate Siri. If plugging into the USB port causes Autoplay to start playing USB media, please note that this can be disabled, or enabled, using the process described in the owners manual.
