Does anyone have any pictures of what the USB in looks like on the back of the Factory stereo? (I have a 2012, and it's wired directly to an upper glovebox.) I'm trying to determine how it connects to the factory stereo. Does the usb cable in the glove back attach directly to a USB in on the back of the factory stereo, or does it have some other type of plug?

Here are front and back pictures of one on ebay.

That helps a lot! Thanks. I'm guessing that the usb input is the bottom portion (as this seems to be a premium option offered by Honda and not on ALL cars) within the little black port, next to the cabling harness?

It maybe a usb port but I wouldn't swear it was for the usb cable in the glove box.
Note the other usb cables listed in the parts break down, in the link above

 

I see, thanks for the links. Trying to determine if using this HU I have with USB on the front, if I can somehow hook up the glove box USB in the back.
