I don't know if we are speaking of the same trim piece. I'll try to explain the best I can. Once you flip down the seat, look where the back of the seat latches i.e where the seat plugs into when the seat is flipped back. Right around the latch is a navy blue plactic piece that surounds the latch. I tried to pry it off (carpet is being held/pinched under it thus not allowing the deck to come all the way off) and it began to crack. I dont think its just a pry thing. I think there has got to be a trick or some kind of tab or something. I just dont want to crack it or snap a part of it off.
