OK first up you need a small pointy thing to pull plastic plug out the one in front once you have this out you well see the first hex head screw to remove. Then remove the whole plastic housing on the font by lifting bottom and moving up two plastic clips at top. Now two more hex head screws inside you'll see them now pull the whole leather cover front first and the back pops out only clips in all done see pic's..............
