I have an appt. at my dealer for Saturday. Since upgrading to the iPhone 5, my Bluetooth connection and Bluetooth audio. I am hoping the update will improve this. It is frustrating to lose your Bluetooth audio while you are driving. There is nothing you can do until you stop and I have not figured out a work around.
I am also looking for the fix of when the entertainment buttons go blank and navigation stops showing the street names. At least the is an easy work around for this issue.
