So the sales manager informed me that one of the packages for my car includes Sirius. However, I get in my car and notice that there's just XM listed on the headunit.

While I was at the dealership the sales guy (those guys that dont know anything about what their selling) told me that the little black dots in the front windshield in front of the rear view mirror were for the anteena. So i also noticed the black little anteena in the rear of the car sticking out. But then, I also noticed this fin-shaped anteena on the roof of the car.

I have 3 anteenas?
Is it possible I DO have xm and sirius?
And if so, how the hell can I tell if I have sirius, and how can i get it to work lol.

 

Those black dots are just black dots, not antennas!

The rod antenna sticking up from the port side aft (right rear) is the AM/FM antenna.

The fin sitting on the roof is your satellite antenna.

 

The port side would be the left side.
Starboard would be the right.
