Anyone know anything about these? I have one and attempted to plug into my truck radio. It works fine but as soon as the ipod is turned on, i get some background white noise that can only be eliminated by turning my treble way down. I changed things and plugged my wifes in and it works just fine with no noise, also my sons. They have older models. I was wondering if im just out of luck or if there was a chance that reformatting the ipod would help.. Well thanks
