The still have tape adapters with the headphone plug on it. I know I have seen them at Oreillys this past week. Just pop the adapter in the tape deck and plug the other end into the XM dock. It will sound way better than a modulator.
Oh I just saw that it is an 8 track. You will need an 8 track adapter to cassette and then put the cassette adapter into the 8 track adapter. They should still have those online somewhere, ebay will be your friend on this one.
