I think the trim piece just pull off, it's held on with those clip things. There might be a couple screw also, it's been awhile. Then some have like four 7mm that hold it in, and I've even seen some that just have tabs that you pinch in by hand. Just get the trim ring off and you'll see exacaly how the radio come out. The trim ring is pretty tough but make sure you pull staight out on the clips and work on one at a time, I have broke a few off before. Good Luck
