my car stereo doesnt like to play my ipod. i have a cassette adapter for the ipod, but when i try to play the ipod, the sound is all faint and muffled and only comes in one speaker. but when i move the end of the cord around the sound will start to work differently and then finally start to play fully through all speakers. i went to apple and they said its my ipod which makes sense because they said the pins inside the headphone jack have gone bad. but when i try other peoples devices like iphones or other ipods it does the same thing. so is it my cord, my ipod or the actual cassette player?
