Xm Module Location

Where is the XM module located in a 2008 sierra? Also does anyone know if it is a one wire antenna or a two wire antenna connection? Thanks!

Directly behind the glove box. Open it and press up on the tab in the center to let it come all the way down.

 

It is a single wire antenna.
