This is an intermittent problem. So will be hard to get the dealer to look at it unless I have some other corroborating stories....

With the radio on, the volume changes by itself. Sometimes only one or two levels at a time. Other times major changes. Today it jumped from 25 to 45. I turned it back down to 25 and then it dropped to 0. When this is happening, the volume control knob on the dash has no effect, I can only adjust it with the steering wheel controls. Seems to be normal for the first 15-20 minutes of my commute, then I fight with it for half an hour or more, then it goes back to normal again. These changes are not related to speed - they can happen at 65 mph or at 0 mph. Turning the automatic volume control (or whatever it's called) off or on has no effect.

Anyone else having the same problem? Has anyone been able to get it fixed? Or do I need to call Ghost-busters?
