They make a kit that goes in the 9 pin connector that your cd player attaches to the headunit with. From what I understand you will no longer be able to use the slave-cd player, but I did see one with a pass through a while back.

They are almost half the cost of a new deck that has the inputs, so that's some food for thought.

Check out the Aux input section:
