Hello, unfortunately I found nothing in the search function: I want to darken the side and rear windows with my XC60 Built 01/2009. The company where I want to do this has now told me that I have double glazing/composite glazing (have bought the car used recently) and that the back does not work well (side windows rear passenger) at the trunk (back and rear side windows) it is no problem. The reason is that the side pane is too thick, and you can’t do well with it… You have to remove the side panes in the rear doors (let) then you could fold it. How do your experiences look – the rear side panes really have to be removed…is that difficult…? Thank you for your tips!
