I have a 2011 Audi A6 3.0T. Recently after an upgrade to iOS8 on my iPhone 5S I have been having connection issues with the MMI. The Bluetooth connection seems to work fine and I am able to receive and place calls and scroll through the address book without issue. I am also able to play music through the Bluetooth connection.

However, through the cable I have regular issues about not being able to connect at all or connecting, playing music for a few minutes, and then having the system hang. I am then not able to scroll through music. Sometimes the system disconnects.

Up until a month or two ago everything was working fine. Does anyone have any thoughts?
