Hey guys when the merger of XM & Sirius is done near the end of the year, you won't need to change anything. You will be able to get both on either reciever. If you do a google search for XM/Sirius Merger you can read all about it. There's going to be all kinds of different packages available.

If you are trying to start XM now you will need to go to ch1 preview and push the tune or vol button until your ID comes up. Then call XM with your ID code. It takes only a few mins to do. I have XM now in my H3 and I hate it.

I have Sirius in my other car and it rocks, it's much better, but I'm going to wait a few months and not start removing stuff and changing stuff around.The merger has a ways to go yet, however they are real sure it's going to happen.

If you do want Sirius now check out Crutchfield. They have Siuius box for GM. They say the XM box is behind the glove box??? I droped my glove box door to the floor and all I see is A/C stuff. I think it's above the glove box.I pulled the passenger side dash panel next the the glove box and I think I see it up there...

Go to the reviews section for thr Sirius box and there is a lot of good info there. People say that the roof mounted XM antenna that came with your Hummer works fine for the Sirius, you just need to remove the yellow clip on the connector. They explain a lot about it, but it's GM in general.....Good Luck
