I am getting a nice deal on a 2006 Mega but I am going to change the stereo to an aftermarket unit. What are you doing with the two half-circle cutouts for the knobs that are in the radio trim plate? I am thinking of ordering a head unit from Crutchfield but dont want there to be two "ears" on the sides of the head unit once I install it. How do I fill the half-circles and keep my dash looking good?
