Hi All- with the panaromic sunroof option does the GLC roof rack cross beams fit? If I add my Thule roof box to the roof rack is the operation of the sunroof possible. Is the operation of the panaromic sunroof possible with just the cross beams and no box? I am regretting adding the panoromic sun roof as did not know it may impact addition of roof cross beams and a roof box- any suggestions on how to make a roof rack cross beams or roof box work appreciated. Is the MB roof rack cross beams good or is a Thule set suggested. New to this so any advice appreciated if someone has worked through this same issue. Thanks
