Ipod autoplay

My search skills must be way off because I am sure I remember seeing this, but here we go. Last year after getting my wife a Ipod Classic for Christmas I talked her into switching from the FM to a dice. We love the sound but find that when starting the car the ipod automaticly starts to play. Is there a setting on the dice that would prevent this. We listen to a lot of books and end up missing a bunch if the radio is off or turned waydown. I do not think that my Nano has this problem it is only the Classic
