It's odd in that Phil1824 has a new iPhone 6 Plus with IOS8 and he is OK. And on the Apple Forum many people had problems with IOS8 and Bluetooth in their car systems but reported that resetting network settings fixed it. I will watch the outcome with interest as I have held off from updating to IOS8 because there always seems to be initial problems and I've learned from bitter experience to hold off. The "if it ain't broke don't fix it" philosophy applies for me. I do hope that it is an easy fix and not an Audi MMI one as if so it could task some time.
