denvermaxxss

I just picked up an 06 maxx ss w/ 41k miles. There is a squeak that comes from the middle of the dash around 40-45 mph. Once it starts it is really loud, but at slower speeds there is nothing. I can't find it and have no clue what to do. Do you have to take the dash apart?

Can anyone give me any ideas? Is it better to just go to a dealer and have them try? Any help is appreciated. Thanks.
