Regardless of whether the stereo is a Cassette or a CD player, if it has AM/FM radio capabilities, it's able to operate in the radio frequencies. I think you'll be able to find such a device with a well-placed Google search, but if you can't, then let me know and I'll see if I can find one for you.

I recommend searching the Apple store first, as you'll probably find it easier there. If not, other companies might make the same thing. I just don't remember the name of the actual adapter. It's basically an RF transmitter. Costs about 30 dollars or so if I can remember correctly.
