Imagine having a factory radio that cannot be replaced with anything else. That's the situation with a 2002 Buick LeSabre we bought from a friend a few years ago. The factory radio is wired so deeply into the electronics of the car, that it must not be removed. I've checked with local radio guys and Crutchfield, and there is no replacement radio available. I bet a clever guy could relocate the radio and leave it wired into the car and install another in its place, but I'm not about to get into that. What were they thinking?
