I have a 2012 TE with the Entune System. I also have a Nokia Lumia 928. Every since I had the vehicle, the Entune system would switch to BTSA 15-60 seconds after I started the vehicle - most of the time.
I went in today for my 20k service and floor mat check. I noted the problem to the service advisor and asked them if there was a new software update for the radio. Of course, the service advisor comes back and says that the tech said it was normal. I politely said I don't understand why, and asked the service advisor to speak with whoever is the authority on these matters. About 20 minutes later, I am told that there was in fact an update, and that it was installed. So far, I am not experiencing any more unrequested switches to BTSA.
FYI, the radio now says that it has Software Version 3.2.0
