If you look carefully on nissanusa.com, when you view the 360 degree image of the car, you can see it has one of the bmw style sharkfins on the roof. Is this for sirrus? can they be purchased? looks kind of sweet!

 

It's for the sat.radio system.You can probably get it for the z pretty soon.I cant look it up on reynolds yet so I would have to manually put it in and see. They should already come painted.I'm too lazy to see if a note has came down on it yet from nissan.You may have to have the 6 disc bose for it to work from nissan.

 

That would be sweet. I wish my FX35 had that too

 

I had a new stereo system put into my car that includes a Sirius-ready head unit and the Sirius receiver and antenna hard-wired in. I had them put the little (1" x 1") Sirius antenna on the one side of the rear strut bar and run the wires under the plastic panels. Signal reception is very good (except for cloudy days, trees, tunnels, etc.) and it doesn't require having something stick up out of the car like a shark fin.
