hi i have a chevy cruze 2012, when i plug in my iphone it takes about 10 to 15 send to index music, and i ALWAYS hear Crackling Noise During Music Playback, its not constant crackling and popping noise but from time to time. i tried different cables and different iphones and ipod touch and the problem is still there, all cables are original cables and the iphones were non-jailbroken, even tried to restart iphones and try again, the problem is still there. please how can i fix this ??
