I have a bit of noise, but I believe it is from the rack rather than the sunroof. Think I'll remove the cross bars, since I don't use it much. The 300M is considerably smaller than the 743; but it is the largest size Holandia-Webasto recommends for the VX. The installer told me they could put a larger one in, but that it would "reduce the structural integrity of the roof". I didn't want to take any chances; and didn't want to lose any more head room. I am only 5'8" and I can't imagine how you taller guys fit. It works great; well worth the dough to let a little air and sun in. I haven't figured out how to leave it open when parked though, closes automatically when the key is removed. I also think they messed up the overhead dome light during the installation, since the push-on switch only works intermittently now.
yeah, I was told about structural integrity too but Tones argument about "sunroof cage effect" makes perfect engineering sence to me. By installing sunroof you are actually increasing the strength of the construction.
