Auto Volume on Radio

[DRTYFN]

I have come to the conclusion that the auto volume feature is non-existent. One my first H2 the techs went so far as to replace the radio with no results. The auto volume worked perfectly in my Tahoe.
One thing that was cool on my first H2 was that when the radio was in Spacious mode and I hit the auto volume button on then off and back to on it would boost the bass in the system. My new H2 doesn't do it though.
