Anyone using a Thule box with OEM BMW bars
 

Is anyone using a Thule roof box with the OEM BMW roof crossbars? Does it fit correctly. I am looking at the Thule 686B with the BMW OEM roof crossbars or are the Thule aero bars better?

I know this is an old question...but thought someone might benefit from the answer. Yes, I'm using a Thule cargo box on my oem bmw crossbars. The only thing you need to do is make sure that you buy longer screws for the Thule as the original installation screws are made for thinner crossbars (ie. th4e Thule or Yakima bars).
