Usb Inputs on non jbl head unit

I had another thread about adding a aux/USB cable to the center consol. In that thread someone mentioned that the jbl head units have a 2nd USB input at the head unit.

Does anyone know if the non jbl head units also have a second USB input?

I asked in that thread but no one knew

 

Mine doesn't...just the single one below the HVAC.

 

My JBL doesn't have 2 USB inputs.

 

I'm talking on the back of the head unit, not a connection out on the console

 

This is the best i can do for you. Thats the back of my non jbl headunit. I dont recall seeing a USB port but i wasnt looking for one and it is possible there is an unused one hiding below all of those wires.
