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.

The Command Console just stopped working, won't turn on. Taking to the shop today. What should I expect? Bought it two days ago.
