annoying vibration with sunroof open

While driving at speeds 0-30 with the sunroof open I hear a very subharmonic vibration or hum. It's really noticeable with the radio on. My passengers have heard it too. Alignment?

Amazing info
I had my S4 for 4 years and never knew that. When I bought the RS6, the salesman told me about it, and I felt so dumb. Goes to show you that I should have looked closely at the manual.

Its caused by the airflow producing a vortex, which results in a harmonic hum. Besides...
slightly closing the moonroof/sunroof, an aftermarket wind deflector mounted on the front edge would probably eliminate the problem. BTW, my '96 A6 does the same thing.
