first dalejr00 i want to say what a great video you made. I am really lost as to what is wrong with my radio so me offering you any opinions would be like a blind man leading you. It sounds to me like some kind of feed back and if i were to offer an opinion and would not be accountable for it, i'd guess it was the amplifier. But like i said i'd be guessing. I can't get over what a great diagnostic tool that video is. My car does not have the screen that yours does. Let me know what you find. Where did you get the used parts you speak of in the video.
