Hello everyone, i purchased an x5 4.8is with what i think is dsp....sounds very echoe so i went in the dsp and lowered the level not so bad now. the guy before me put the dice ipod interface inplace of the cdc. when i bought it my iphone 3gs did not work so i needed my tunes and uplugged the dice and replugged the cdc but it had a six pin and not the coaxial so i plugged in the six pin and now the cdc sound comes out of the drivers side and very very low on the passengers side. but the radio and tape sound is equal on both sides its just the cdc that sounds terrible.....any help? am i missing the coaxial to connect from the amp to the cdc?
