2011 GMC Sierra with stock radio issues

[iownatundra]

Good evening! So this weekend, while visiting a friend in Washington, I was using his 2011 GMC Sierra (I believe its an SLE). I accidentally left the headlights on, and when I came back to the truck and tried to start it, it just clicked. I called him and he brought jumper cables. It had been about half an hour by the time he got there, and I hit the key, and it started (barely).

 

The problem is, now the radio won't work. The display will show the time, but the radio itself will not power on. No am/fm, cd, aux, nothing. Also, the USB port below the stereo is no longer working, and the chime for the turn signals isn't working either. Anyone have any ideas? I'd love to be able to fix this for him before I leave town.

 

Thanks!

I don't have an answer for you, but I hope I never leave my lights on if this going to happen to my truck.
