2015 Mercedes GL550. Has anyone gotten this sound while driving? I get it almost every day, it also depends on the weather outside. It merges in the middle of the Car, if sat in the driver's seat, I can hear it on my right, if sat in the passenger, I hear it on the left. I have covered any gaps in the side mirrors and the door, but the humming is still there.

Here is the URL:
If you have any suggestions on how to solve it, please do comment.

Thanks

My friend's '05 Ford F150 does that (rarely). Seems to come from the windshield/hood area, like blowing across a bottle top.
When did this start on yours?

Thanks for the reply. It started last year, but I noticed that it didnt happen during winter weather. Somehow it stops. Throughout Summer it was just crazy.

Turn of your command center to see if it is amplifier noise

A troubleshooting trick that I've heard of other people trying is to put wide tape (like they use when installing a windshield) around the perimeter of the windshield and the leading edge of the sunroof to change the airflow to see if that is causing some resonance. If it changes the noise, then remove it one section at a time until you narrow down the source.

I have played with the command and has nothing to do with the sound system.

Have you checked all your belly panels to ensure they're properly mounted? Might not notice that one is loose when there's not a 60mph breeze pushing it around.
