There are adjustments for bass, treble, balance etc in the MMI on my 2009 S5 with B&O. There's no equalizer, but there certainly are the basic controls mentioned above. I was just messing around with them tonight as a matter of fact!There is no bass, treble and balance dials on the S5 with B&O, even with MMI? That totally blows. (BTW, Firefox is run my Nazis, its spell checker lists Goebbels as the recommendation for trebbel, lol)
