First post since buying.

Question: Tucked under the passenger visor is a wound up small gauge wire that ends with a USB flat connection that is the end you would use to plug into a port, not the end that plugs into a device like a phone for example.
The wire leads down behind the A pillar cover. I have no idea where it terminates. The cable is long enough to plug into the center USB port between the front seats. Nothing seems to happen when I plug it in. No, change to the AUX connect for media.
I am perplexed.
Any ideas what it might be for?
