yeah, I have a sunroof. the fairing is over about 1/8th of the back portion of the sun roof (actually, maybe not even that much!). I can still open the sun roof just fine as the fairing has a few rubber feet at the bottom of it so it doesn't scratch or rattle on the glass. the only downside is when the sunroof is open, the fairing forces more air directly down on the driver/passenger than it would normally without the fairing... this doesn't bother me but it is something I noticed when driving with and without the fairing. all in all, I love the setup!
also, I'm not sure if you noticed, but I still have my factory cross bars on. I didn't have to remove them for this setup.
