you mean that little pannel under the headunit in that little hole?
if so, that things soo easy, haha, youre not gonna break it, nothing to worry about. if you reach all the way down, youll feel a place on it where its cut away, that was put there so that you CAN safely remove it without breaking anything, just pull it back and it pops out, then you have to gently tug the top clips, if they dont come out when you pull on the bottom.
