You can even use the Bass, Treble, Fader and Balance on your radio! This radio is fully rebuilt and all of the lights in the face have been replaced with brand new bulbs. All features are 100% and appearance is great. The display screen has a protective film on it. This radio requires dealer turn on upon instalation.
