XM Radio Kit, Dumb Question?

[Erod]

Fellas,

I know this forum has been a great source of information, but I have a question to ask all of you. I can't seem to find the KIT for XM radio, I seen it here, but in the search function comes out with hundreds of options. So do any of you know where this topic is. I needed for the guy I sold my 2003 H2 SUV. He wants to install XM radio, but I told him that there is a kit available now, and I can't seem to find this link. Can you guys help me? Thanks in advance.
