2012 Navigation unit
I'm thinking it is some kind of a data port?
From Ray Kawal: "Next you'll need the radio USB cable: This is GM part number 22828130, and it costs about $45. You need it because the USB connector on the radio is a proprietary connector and this cable is specifically designed for the USB radio. The USB connector is called a "mini-A", which is available in other places, but a regular "mini-A" won't snap into the radio housing without modification. Get the 22828130 and you'll be very happy you did."
