Mildly annoying buzz

Howdy all.

Loving the trophy, such a great package!

Anywho, I have a slight rattle/buzz coming from the little side vent above the drivers air vent when on less than smooth road surfaces. Gently applying pressure makes it stop straight away, wondering if anyone else has this and/or fix?

Can drown it out easily enough, but would like to fix it without sending to a dealer to rip out dash and make a pigs ear if I can help it.
