I really want the panoramic sunroof, but apparently the factory rack cannot be attached to this as the inner portion of the mounting foot would actually sit on the glass. So I'm stuck with buying Yakima Q-towers for mounting on the door frame. My question is--with the q-towers (or thule's version), is the sunroof fully operational? The q-towers do have a relatively small area of movement when installed, and on some vehicles the crossbar actually still sits in the way of opening glass on the sunroof. Meaning that the opening glass will actually hit the bar. Can anyone help me with this on the Venza? If someone can actually tell me how far the glass elevates when the sunroof opens, that would be a start. thanks
