Bought a 2013 SE today, while XM isn't installed on the car, it has the antenna on the rear of the roof. Question is, is the antenna wire there, and can I get to the connection to use it on a stand alone XM unit that I have?

 

Well, after having time to take a closer look today, it seems the dealer made a mistake. They told us it didn't have XM, but it did have hands free. He got it exactly backwards. It has XM, but not handsfree. So I transferred a subscription from a stand alone unit I had been using to the Charger. Wife is happy now.
