If you have a cd changer hook up you can do it. Just go to radio shack and buy an audio(red/white) with headphone jack cable. You should have this as most stereo hookups do. It is a cheap cable. You could spend $30 and get the monster cable.
Chris, I have an 05 X-45 and have cd changer hook ups. More then likely so do you. If you look behind the actual cd deck underneath you will see the red/white hook ups. You will have to crawl in the hatch and look up to see it.
