Bought the car a year ago used and the CD changer won't eject and the console won't acknowledge the changer exists. No voice control anywhere to speak of.

CD changer in Control panel just shuts down then the whole control panel needs to be stopped and restarted for it to work again. I haven't had it diagnose because I am broke from fixing airmatic suspension issues with just one strut.
