First thing I would do is check (or, have someone check) the grounds on the radio and everything else, too.
I've started getting some alternator whine and other noises in my AM radio (2000 Subaru). I noticed that there was a (apparently) burned out light bulb in the dashboard, by the heater controls. I had the dealer check for a problem with the noise/grounds and the alternator, but forgot to mention the burned out light. A few days later, I had to switch from A/C to heat again, and pushed the slider hard...the light came back on!
Slapping the side of the console makes it come on and off, and the radio noise level changes, too.
Sounds like I'll need to pop open the side panel on the console, and see if there's a loose wire. If your noise is getting in to everything, though (not just radio), you might also have the alternator checked.
