I believe only the newer Passats have the Monsoon logo on the cassette door. My 2003 does not, but 2003.5 seem to all have it. 2003.5 also do not have lights in the air vents like the 2003 do.JimmyDee said:As Paul said... if you look at the slot where you insert the cassette, it says Monsoon on the cassette door. It also lights up Monsoon on the display every time you turn on the stereo.
I'm guessing you don't have a Monsoon... otherwise you'd have noticed these things.
