you have to take windscreen out and remove door and boot seals and sunroof trim and handle if applicable..'c' and 'b' post trims also need to come off along with rear quarter glass windows...unpick the head lining off the aperture under the seals(door boot etc)..it will the sag down either end and be held up in the middle with the fixing rod/s..bend the rods gently in the middle downwards and lift the end of the rods out the locating holes..you will be able to see them if you look when it been unpicked from aperture..fitting is reverse of above but a bit more awkward..i used double sided tape to refix edges of headlining to the aperture..make sure its on well at the front because when you refit the windscreen the rubber tends to drag the headling with it and it goes saggy..be careful with the edges of the lining when removing/refitting because chances are it will be brittle and rips very easily..a hairdryer is good to use to help remove/reduce creasing and baggyness when fitting
