I already explained why it's there. It provides a cellular link for the Onstar help and car phone, and satellite link for navigation and other locations services.

Because the roof is curved, the tip of the antenna actually sits at the same height as the tallest point on the van.
So do all these things come with a new van or is it a option that you buy separately?
Like I said before my cell phone has no problem working in a car so I don't know why I need a separate antenna for a phone to work. To me the look of a little Black Finn on the roof of the van looks stupid.
The first thing I'd do is take it off. It's not needed where I'm at. I don't need navigation a separate car phone, emergency services ect. I live in a place where it's a hour from one side to the other.
So I just picked up a set of these awesome Silverado wheels on CL for my 3500 motovan and was wondering a couple of things:
what sized tires are you running?
what if anything did you do to lift/ level your 3500?
what did you do to them to make them gray?
