Both my IceLink Plus and my DICE give a whinning nosie while on. I re-ran my trunk cable to a different route, and the noise is still there. My local car stereo shop suggested a ground loop isolator or something, but they didn't know how you'd use one since there were no RCA inputs... Any suggestions? The noise is driving me nuts... I just plugged my ipod into my OEM AUX input adapter (no noise then).
