My 2007 Sport, purchased a few months ago, makes an occasional buzzing noise from where the factory radio is located in the dash, usually when I'm going over a rough road. It's not constant thank goodness, but when it does happen it's very noticeable. If I press it with my hand around the digital display, I can usually make it go away or at least reduce it (and yes it happens even when the radio is turned off).

I'm a novice at best with this kind of stuff, but I watched a couple videos on how to remove the radio unit in these cars and it looks doable, so I'm thinking of removing it to see if anything seems loose, etc. But first I thought I would check if anyone has gotten a noise like this and if there is a certain spot on the radio or in the dash that's a likely culprit. Thanks

 

check your grounds that could be issue with static.
