I have a intermittent, but consistent problem with my radio/nav unit (GM part #1580001) having volume spikes and the screen going black as shown in this youtube video:

It has been viewed more than 1500 times, so I'm assuming others have this same issue. I have read many posts and no one has come up with a solution. I've pulled the radio, checked all of thewires, disconnected the 6-disc changer, and nothing has resolved the problem. Been to the dealer twice and they say they can't find anything. Some posts say that they had the dealer replace the head unit only to have the problem occur again a few weeks later.
The one post that intriqued me was one that claimed the problem was related to the vehicle's electronic suspension system. This somewhat makes sense because of the seemingly random times that the problem happens.
My question: Has anyone figured out the root of this problem and a possible remedy?
Thanks much for any advice.
