I have a 2020 ecoboost coupe. I have read numerous threads on the internet about how to disable the ANC. Whether that will make a difference in the droning noise I get in 10th. gear, I don't know. Opinions seem to be divided. Anyway, they all talk about pulling down the headliner at the rear and then you will see a microphone a few inches in and in the middle of the headliner. I have done this procedure and there is no microphone visible. Is there any other place where this mic might be? I know the convertibles have the mic in a different position but I haven't seen any other locations for the coupe. They also said I can pull the fuse for the amplifier, which I did. Of course I now would not have a radio. I pulled the fuse anyway and I did notice a substantial difference in the drone noise in 10th but now there is a different drone at other speeds, which is very annoying. So, I put back the fuse (a very annoying job) and I am back to square one. I'm thinking that if I disable the mic alone, that could make a difference in just the 10th. gear drone.
