Start with the trims that run from the front to the rear.
Stick your fingers under the side trim at the top of the windscreen, gently pull it up until it gets out of the upper side clamp, gently pull the trim out of the two lower clamps (beware and watch out: the trim will stuck under the front fender edge, so you can take the bottom part of the trim out yet).
Pull out the trim along the roof clamp by clamp and after the last (rear) clamp let go of the trim, you can take it off the car.
When you have removed one roof/windscreen trim, you can remove the upper windscreen trim by gently pulling it out of its steel clamps starting at the side that is freed from the roof/windscreen trim.
