2020 Silverado wind noise

[Black Widow 1957]

I get excessive wind noise at speeds above 70mph when the wind is blowing. Seems to be in vicinity of XM antenna location. Anyone else with this problem?

What do you mean by "wind noise"? I posted yesterday (in the HD forum - troubleshooting) about a whistling noise seemingly coming from the roof area, at speeds above 80kmh, on a new 2500. Thought it may be from the area of the antenna and/or roof lights, but as I just received the truck a couple days ago and I am about to leave on a long distance road trip (and it's raining pretty heavy which makes it harder to hear), I have been unable to fully investigate.
