Can you tell from looking at the G if it has sat radio or not? On other cars you can see the "shark fin" and I don't see anything like that on the G...

So where is the antenna located and how would one know if the car has that option?

 

Mine is located on the roof, in the middle, just in front of the rear glass. Came from the dealer that way.

 

Ok, thanks, I will look at the pictures of the roof again.
