Does anyone have the diagnostic procedure for getting the speakers to work again. A member told me about twisting the throttle 3 times with the ignition switch on and that brought one of the front speakers on for about 30 seconds. Some one else said there is a procedure that resets all of your equalizer settings etc.but provided no instructions. Can anyone help? I have also tried disconnecting the battery leads which did not work. Pressing one of the top buttons also resets the radio tone however I understand that pressing a series of the top buttons in some sequence resets certain parts of the stereo. I currently only have one rear speaker working and 3 are T/U. Thx in advance. My ride is a 2005 LT with 19K miles.
