FWIW, I was able to get the black oval backing off without removing the grille. Pop the hood, on top of the radiator area there's a plastic piece going across the top of the grills. It's held on with a bunch of pop-fasteners. Use a small screwdriver and pop those out to remove the plastic covering. Then reach behind the emblem, there's 3 or 4 tricky little clips that require a small screw driver to pop out. Don't have a picture on hand, but undo those clips and the oval piece, with emblem attached, will slide ride out. There was also a Phillips screw there, don't remember if that had to be unscrewed or not.
