You can have 2 items connected at once via usb. Besides the usb in the center console there is one on the left side of the glove box. I have had a usb in the glovebox and my iphone connected via the usb.The one in the glove box is the usb that needs to be used for updating the software. Also the glovebox usb is the usb you need to use to store music on the internal HDD.
