This is the main reason I hate those totally-integrated stereo systems. Yeah, they look good, and modern decks sound pretty decent unlike older stuff that was always begging to be upgraded with aftermarket. But things will go wrong, and you are at the mercy of the dealer (or junkyard) for a replacement headunit or amp if there is no way to get deep inside and repair the original. I think 80 percent of CD headunit failures are from the laser dying.
