For everyone that has patties with noise heard by the B party at speed and not when car is stationary. I pulled to cover above the mirror where the microphones are and I put on top of it a half inch thick sponge layer. Put it back in. Best BT I ever head on any car by far. Too much noise coming in through the glass roof.
I tried pulling down on the cover a bit but I'm afraid to break something. If this really is a good solution, I'd love to see a pic if you get a chance. I'm sure a lot of others would too, since this seems like a common problem!!
