Also, are you sure it's not the passenger headrest rattling? Mine rattles like crazy and when I hold my hand on it to steady it, the rattling stops. I managed to work a position on the drivers headrest that is both comfortable for me and inhibits rattling, but no luck with the passenger side.
That unfortunately describes that buzz rattle to well: like a quarter spinning inside my dash.
I'm not 100% sure about the headrest, but if it is the cause, I haven't been able to stop it with my hand. I need to explore more.
