2014 XTS V-Sport Platinum
So, the AVC isn't doing anything at all in my car. Going through the list of service records and things that have been done on the car, I noticed mention of a sunroof leak that resulted in water dripping from the overhead console. So, I am thinking that the Bose microphone up there may have gotten fried. Can't find any sort of troubleshooting for it in the FSM. Should I just buy a console and see if that fixes it? They are going for $50 on eBay, or are there any other suggestions?
