I HAVE AN 06 TC AND I JUST ORDERED THE D3, DO I NEED TO GET A WIRING HARNESS? DO I NEED TO GET THE PIONEER IPOD DIRECT WIRE OR CAN I USE THE ONE MY SCION ALREADY HAS? DO I NEED TO GET ANYTHING SPECIAL IN ORDER TO USE THE STEERING WHEEL BUTTONS? I JUST ORDERED THE HEAD UNIT, IS THERE ANYTHING ELSE I WOULD NEED TO BUY, THAT DOESN'T COME IN THE BOX, IN ORDER TO INSTALL AND BE READY FOR USE.
