Speaking of things MFT does that make me crazy: get in wife's FoFo, start it up, put seat belt on, drive away. One block later, it's disconnected from wife's phone (back at home). Does it try to see if it can connect to my phone? Nope, that'd be too hard.
I understand connecting to the default phone when the car is in the driveway. I don't understand not trying to connect to anything else until the next time the car is turned off and turned back on. This is another thing that worked better in both the 8 year older Acura and three year older BMW no name audio systems. Who would have thought the 2012 top-of-the-line state-of-the-art MFT Powered by Microsoft Sync would have been so lame as to not do this correctly?
