Hello all, my first post here. I've had a recent incident that involved a automatic carwash ripping my SiriusXM antenna off my trunk. To my knowledge the car has the factory default radio with 6 cd changer.
I've taken the radio out to look at the antenna's but it has 2 antenna cables. I know one is the FM\AM antenna and one is the satellite antenna. It looks like both run down behind the radio and climate control under the center console/armrest.

The satellite radio antenna was located on the passenger side of the trunk (magnetic antenna) it ripped off and was lost. I've been trying to figure out how to replace it. I can buy another but I'n not sure how to hook it up.
I was wondering if there was a tuner box the magnetic antenna hooked up too is there something else. Me and My father is still trying to learn about this car. Hopefully someone can give me some info to go on where I can get something going to get the antenna replaced.
