If those can be serviced from the top like it appears, you can remove both of the glass panels and then the sunshades. I just did this operation on an E61 which uses the same pano roof as the E70 in order to do a suede headliner and replace a failed pano roof seal with an updated part (that job SUCKS). I thought I had a .pdf for removing the glass panels as well but it's pretty easy to find via google.
