Ford Sync 3 USB connection broken with IOS 11.2.5

After updating IOS to 11.2.5 usb connection to Ford Sync 3 no longer works with native Sync 3 OS running.

With the Ford Sync 3 system audio and maps can be either Apple Carplay or the Ford Navigation and Music program. If one is to run the native Ford Music and Navigation program Apple Carplay must be disabled.

The problem is after updating IOS, the USB connection for the Ford Sync 3 music app no longer functions and even blocks the ability to use the Bluetooth connection to the iPhone on the same app. Siri is down at this point also. One must disconnect the USB connector to allow the use of bluetooth to connect to the iPhone for the Sync 3 music app. After the bluetooth connection is established, the USB connector can be reattached to charge the iPhone and use Siri. Also, the button to select USB for a music sources reappears on the Sync 3 Music Source page, but if you select it, it locks out the iphone again in both USB and bluetooth. Then you have to disconnect the USB connector again so you can select Bluetooth again.

This problem was replicated in two different Ford vehicles with the Sync 3 system.

If Apple carplay is enabled that system works fine.

Prior to IOS update to 11.2.5 everything worked fine.
