Unfortunately, the TSB for the Auto Volume does not work, at least my dealer has done plenty of the wire switching, but not one has worked. I took my H2 in yesterday as the radio stopped working completely (the second radio in my H2) and the Service Tech told me that the only consistent problem with the H2 and all of the GM vehicles using the same radio that we have is just that --
"THE RADIO" ... the same radio is used in the GM trucks, Buicks, Oldsmobiles, Chevrolets, and the like ....
