I also have a similar problem with my Edge 2011. And the problem is not static, it evolves in one way or the other !
Started with an issue with Voice recognition not working when the radio was on. Then the problem simply disappear by magic. Now, I'm not able to pair by Black Berry anymore. The pairing starts, the number appears on the screen and then a message says that the pairing failed.
I have talked to the Operation Manager at my dealer in Montreal. The guy got instruction from Ford not to attempt any software/Firmware update until further notice. The update could actually make it worse. He hopes (and I hope as well!) that a bulletin from Ford will come shortly with instructions on how to update the system.
Annoying indeed...
