close but not quite

For a 2011 genesis coupe with nav and auto climate controls: The black color is not the same as the stock dash. The metra piece is more of a flat black. The cutouts for the hazard and airbag light are pointless. Those are located along the bottom of my center speaker. I have to fill the metra holes with bondo and sand it smooth. The pioneer AVH-5600BHS I just got, does not fit the metra opening. The headunit is about 1/8 inch too wide. Height is not a problem though. I was not expecting to have to use the dremmel. Unfortunately there are not many options for my situation.
