The system will seek to connect back to it's previous audio source without having to do what one person described fantastically as the "bluetooth dance"
If you don't have nav I'd really suggest downloading it if you are having problems. It has been a great improvement for me. I believe once ios 6.1 comes out and fixes a few issues on their end I'll finally be happy with MFT.
Not sure who you're responding to, but this TSB has nothing to do with TSB 12-11-01
