Radio works fine, CD changer loads CD's and goes thru the tracks but there is no sound, not from any of them. I searched but it looks like i'm the only one who has this problem. Does anyone know what the hell is going on? I don't understand how its loading CD's and I can go thru the tracks and fast forward and everything but no sound comes out. This pissing me off!! Everytime I fix something another thing breaks. I just dropped $200 at benz to get my heat to work TODAY and now this breaks!
