Mine was doing similar things, after digging thur ford pass I noticed the sync required an update. Had the dealer do the sync update when it was in for the last recall. One of the 2 fixed it and working normal again
Mine did not work, so took it to the dealer during one of the recalls. They found it was not plugged in under the truck bed. Plugged it in and strapped it to secure it. I guess the factory forgot to do this
