so i bought another kca-420i ipod adapter for my HU...being that the first one i got off ebay didnt work. low and behold it still doesnt work. i cant get the HU to recognize it. the switch on the bottom is in the correct position and AUX input is on. this was my ex's HU and he had it set up with the ipod adapter and it worked fine, so i know it can work. thanks all
