I have a 2003 Chevy suburban. I’m trying to use the factory xm antenna and installing it with the xm tuner I have for my aftermarket radio. The problem is that the only videos I see to do this show one yellow connector going into the stock receiver behind the glovebox. The receiver in mine has a blue connector with two separate wires in it. Does anyone know which one is the antenna so I can plug it into my xm tuner. Thanks

 

Using the images from BestBuy, you can get an idea what an aftermarket radio wants plugged into it. I was about to buy one of those. I could of sworn they were $35 last year,
May help if you tell us which aftermarket radio you have. They normally do not come with a XM tuner, just a connection to add the one from the above link.
