XM/Sirus work just fine. You need to get the vehicle kit, if it didnt come with one. It powers from the 12v above the cup holder. The best place I found for the antenna is on the dash, toward the windshield. I have mine 3-4 in away from the windshield. I ran the antenna wire from the base under the dash, behind the radio and onto the dash. I ran the 1/8" stereo cable below the radio, using a flat head screw driver to push it below the line between the radio and the dash, and into the glove compartment. The door will close and lock.
