I installed my head unit this weekend and I knew it was too easy. I have the unity in and it sounds great but the only problem is that the outer ring trim piece that goes around the cd player will not go on. The problem seems to be that the sides of the trim piece will not fit into the cut out for the radio on the dash. I was looking at other peoples installs and the trim piece looks like a snug fit there also. Did anyone else have to trim to make this fit?
