You can get one of these for a remote hdmi/ usb port - cheaper versions available. 15 ft of cable but unfortunately when I went to retrofit I hadn't left enough for the connection.Stop it, wires are easily hidden, Xbox under the rear passenger seats, wiring hidden under the carpet up behind the side panels and then into the screen, easy peasy.
I run a tv tuner to mine which is under the front seat, one of these.
