Hi, I have a 2011Edge with the Touch Screen Sync system, No GPS, though. Since yesterday, my stereo is not even an option on the touch screen to turn on. If I hit the master power button on the rotating volume knob it makes the initial sound like it's about to come on, but nothing happens. I checked the fuses for both the stereo and the amps along with a few others but they all seemed fine. Any help would be highly appreciated.
