The passenger armrests got 2 cutouts. 1 for an iphone 5 and the other for the headset box controller. These 2 cutouts got a thin pad of sticky backed foam for looks and function. I then installed the plexiglass nosegear window and the fuel selector panel along with it's hardware. Finally I installed the passenger Ipad mount on the back of the headrest and installed the air vent eyeball.
