I'm Wanting To Get Xm But When I Do The Registration It Is Asking For A "xm Radio Id". I Have The Antenna On Top Of My Truck So I Know It's Capable. Does Anyone Know Where To Get This "id" Number

should show up on Channel 0 or 1

I Have A Gm Stock Stereo. How Do I Get The Id Number From It For The Xm

same on stock radios also. XM list the instructions on there website.
