Yeah I have my doubts too that the MFT upgrade would even address the BT handsfree because the MFT update was not vehicle specific. For all we know the Taurus, Fusion, Edge, etc all have great sound quality on the highway and no customer complaints.
Robbie - If you get a chance to dial into your VM or something where you can play back your own msg from the car. Please let me know what your thoughts are. I know your only going based on what you've experienced and I would really like to think that the MFT had something to do with the improvement.
