Adding iPod kit to standard 2003 head unit.

[guest4319]

My wife has recently bought a 2003 Honda Jazz with a cd player in it. She wants the option of listening to her iPod without replacing the entire unit. I am eyeing a Dension Gateway kit to go in my Civic at some point, is there a disc changer port on the rear of her Jazz head unit in which she could plug in such a kit?
I have seen the GTA Car Kits video for adding such a unit in the later Jazz, is fitting a kit in the earlier Jazz my wife owns a very similar process?

many thanks
