Aux-Input adapter for a Cassette Changer Input?

[Kofo]

I have a 1997 Pontiac Sunfire with a stock stereo that has a indash CD player. I've been looking a long time for an option to connect my iPod to my stereo. At first I thought the GM9-Aux would work but then I find out that since I have an indash CD player and not a Indash Cassette Player, it wont work. They told me even though my car has the needed 9-Pin input, the input in my car is for a Cassette changer and not for a CD Changer. SO, are there any Aux Adapters like the GM9 that plugs into the Cassette Changer input instead of the CD Changer input.

Thanks and sorry if it's confusing...

WTF is a cassette changer?

I guess it's kind of like a CD changer, but it uses cassettes instead of CD's.
