I just bought the BMW Communication system for my 2011 R1200RT and my Schuberth C3 helmet. When I play FM radio, the sound quality is relatively poor and distorted if you turn on any bass above 0, but when I plugged in my iPod, the sound is extremely distorted and impossible to listen to. I made sure the Volume limit is turned on and the EQ was turned off on the iPod. I have tried turning the Aux volume on the bike up and down and it had no effect as well.

Has anyone had this problem and were you able to fix it??
