Query: Lasted 6 months

I have had this car stereo for about 6 months and today when I pushed a button to change the radio station, the face popped off. The plastic pieces that grip the face and hold it in place have broken off. I have only taken the face off one time in the six months I have had the stereo, so this could not be from overuse. Until that time everything worked as it should. The sound quality was not as good as my factory stereo had been, but was okay.
