I have the 80gb classic. when i try plugging in anything through the headphone jack, nothing plays. i play it from my isound where i just plug it in from the bottom and it charges and plays through these speakers perfectly. yet in my car i try plugging anything through the headphone jack and nothing plays. i have no other problems but can’t hear my music.
