I just completed the DIY. I must admit getting the trim off is extremely difficult. It too me over 2 hours and I consider myself an above average mechanic.
The trim cover is held in place by 5 tabs. Please realize that the aluminum/wood trim is glued to the black plastic peice below (this peice has the tabs). Do not try and pry on the thin cover. Also I had to break all 5 tabs before the cover would come off. Then I re-glued the aluminum cover back onto the sunglass holder.
I read other posters say this job takes 3 minutes. It would be impossible to do a clean job and complete this DIY in 3 minutes. It is not impossible to install the sunglasses holder, but I suggest some patience on getting the darn trim cover off!
