I recently installed Ford's Trip Tunes. While doing so I unplugged my Shaker 500. Now I have plugged it back up and it won't power on. I called the local dealer and he says it has to be hooked up to a computer to reset it, and that it will cost $75. Is there any way around this? Can anyone please help? I have no tunes at all in my brand new car, and no money for a dealer reset.
