Keep in mid the Bluetooth module is located behind the glove box on the passenger right fender dash support structure. Its only being held on by two nuts that screw onto the threaded studs that are welded onto the structure. So I just got my right angled socket wrench and took them off. You kind of have to do a whole 90 degree L shapped turn song and dance to get the module and it's attached L bracket to come out of the passenger compartment, but it can be done.
Hope this helps someone!
Do you have a picture for where this is located? My BT Audio is permanently grayed out - even after battery reset procedure..
