Car Stereos: LS Stereo, lincoln ls, logical problem

Question
I have a Lincoln LS 2002, my stereo works however sometimes it freaks out, it changes stations, flipping between Am FM and CD, I can never predicts when this happens it just happens, has something comes loose like a ground wire ?, any suggestions I would like, thanks,, Sean

Answer
Sean, the only logical problem that I can see would be a sticky button.  Perhaps one of the buttons got some pop spilled on it or something and it is just a little sticky.  If you check them, and they are all free moving, the problem is probably internal, and the unit will need to be repaired professionally.  Hope this helps, Scott
