Hi folks, I have had a bizarre problem with my 2019 ford edge for a couple of days. The Sync screen is not working (black) for the radio, navigation etc, etc. but the screen itself is working when I turn the cameras on. plus the radio is working since I can hear the music and change the volume, but I am not able to switch the radio station from the main console or the steering wheel. the volume from the main knob and the steering wheel works fine but not the other buttons (concerning the radio of course). any help?
