1. Open sunroof.
2. Loosen or remove small bolt which secures the clip.
3. Slip the clip down and out of the sunroof opening.. DO NOT FORCE OR BEND IT. You could damge the clip and/or chip you paint.
4. Remove deflector.
I purchased my SE November 23rd. I removed the wind deflector because I didn't want it to become a catch-all for leaves, dirt, and other debris during the winter months when the car is likely to go between washes longer. I am going to re-install it this week because the weather gets nice this time of year here in Virginia.
I am not wild about the looks of the thing, but Nissan did a crappy job of designing built-in the sunroof wind deterring deflection components. My 2000 SVT Contour had the best sunroof I ever had. You could drive 75 MPH and have a normal conversation in the car with the thing fully open. And no wind buffeting with the SVT sunroof.
The Alti sunroof is noisey as hell without the deflector and allows a lot of buffeting in the cabin, so you may want to keep it on in the warmer seasons when you are likely to open your sunroof. Check it out both ways with the windows up and you'll see what I mean. The deflector does work really well.
