Audi Concert car stereo system display pixel problem repairs:
LCD pixel problems on the display of the Audi Concert Radio's display is also very common - the ribbon cable replacement solves the problem for good. This cable is usable at those models which were assembled with "Zebra strip" too. The instructions booklet we send together with the cable will include the repair manual of the "radio uncontrollable volume problem repairs" too, which is also very typical at this model.
