Hi, I've not been on here much, and in fact the main reason I joined was to find an answer to the question of roofbars for a Scenic II with panoramic sunroof.
Well, I could not find the answer here, so I am now posting one myself!
I have got hold of a set of Automaxi Supra No47
roofbars. They are just plain square section without locks, but they do the job.
The main problem with the panoramic sunroof and roofbars is, I think, one of vertical clearance when the roof is opened. In this respect, these bars are fine. BUT, they are a bit tight on the sides, so I would advise that the first fitting is done with the roof already open. Mine are so close to the glass that I shall be filing a bit of the upright away before I use them "in anger".
Anyway, hope this helps.
