Hi all. I'm currently having a problem with my lady's beetle's audio system. I can crank it up, then after a few seconds it will decrease a notch or 2, then go back to where I set it, and on and on. Sometimes it works perfectly (rarely) and sometimes it'll only do it a handful of times, but here's the thing: it won't do it at lower volumes. Only when it gets turned up above I'd say 3/8 to 1/2 volume. Maybe less because I'm using my phone mp3 app to pipe into the cassette deck (seriously VW?)and I have the eq set to accentuate the lower frequencies a bit over what a flat eq would look like. I really notice it on harder rock songs than say 80s pop or whatever other softer stuff I don't pay attention to. Was there some kind of hearing protection built into the Monsoon system? I have also noticed a little mss flag on the display that I can't figure out how to turn off. Or am I about to buy her a new head unit? Its a 2000 GLS 2.0 w/Monsoon if that matters.
