your options are to get a tape that has a cord if you still have a tape deck.
try to pull out the deck and see if there are imputs that look like the ones on the back of your tv, if there is then you can just use the ipod to tv cord,
or you can go and buy a fm radio transmitter that you plug your ipod into, it creates its own radio frequencyu so you turn your radio to that station and vuala
