I 2016 Honda Fit and my stereo went black when I hooked up my phone to the usb and now it don't have anything on it but the displays whenever you turn the knobs it'll come up but no wallpaper no lights just the clock does anybody have any ideas what could be going on

 

may sound like a stupid question but I have to ask

 

This thread is ftom a few weeks ago. When you plug your phone into the USB the car is trying to connect with the phone, it is not just a charging port. Unplug the phone and your screen should work. Look in your manual about the ports. They are to connect and play music or for iPhone.
