According to GMC and Chevy's website, the 6.2L comes with active noise cancellation. I've had my Denali for a few months now, and in that time, I've never noticed anything that tells me there is such a feature working. Usually with true ANC headphones, I am pretty sensitive to the dead silence they can create. Went on 550 mile road trip this weekend, and had various degrees of wind and road noise on the drive, with nothing seeming to happen to fix it. At this point, I don't think its working or installed. I have the three mic grilles in the cab, but haven't pulled one to see what's back there. I don't see anything in the HMI's menus to even tell me about it, much less adjust it. Don't see anything obvious in the hidden system menu either. Anyone notice theirs working or any options for it? Maybe I got the wrong programming at the factory?
