Has anyone experienced a massive degradation in road noise cancellation on the speakerphone with 2.9.40? I've had my 2015 85D for about 3 months now and the speakerphone was flawless. My callers would rarely be able to tell that I was in a car, at any speed. Best car system I had ever experienced. When I figured out the volume button acted as a mute button during phone calls I was ecstatic. My car is now running 2.9.40 - I presume it was updated yesterday in a service visit, in part to fix some slight wind noise from the backing plates in the door handles. They did so and my car is quieter internally than ever. However, every call I've made/received since yesterday has resulted in complaints from the recipients and I've had to take the phone off of the bluetooth in order for the caller to be able to focus on me and not the road noise. The callers indicate that the noise increases with roadspeed/road roughness. I've made many test calls including with different paired iPhone 5's as well as calling my local service center Tesla who is researching.
