I've noticed that when I play music with some bass/beat, there is a buzzing I hear above my head in the roof. If I press up against the headliner, it seems to alleviate the buzzing sound. I enjoy classical and soft music too, but occasionally like to listen music with some bass. Anyone else have this issue? Any remedy to it? I'm on the fence about telling the dealer to troubleshoot on my next visit because I don't want them to pull off the safari roof trim while investigating and possibly introduce leak issues (so far no leaks and want to keep it that way). Any advice welcome. Thanks.
