I have a problem with the MMI on a 2008 Q7 that I bought recently. There is no sound coming through the audio and I cannot unmute by using the normal volume controls. I suspect there is something wrong with the MMI display unit as there are a few functions I am not able to access.
All of the buttons on the mmi control console seem to work at least for something, but not for everything. In trying to access the sound, the control button lower right does not do anything, and yet if in Nav mode, this same button will switch you back to map. So the button itself is functioning.
Access to the hidden green menu is not possible, because pressing the car and setup function selector buttons simultaneously does nothing, yet individually each of these buttons work.
Does anyone have any information that will help me? Please.
