This was the hardest, worst sentence I think I have ever read.

Is your truck a GMT900 or GMT800?

Is is a base model?

What exactly did the dealer say?

Do you have onstar?

I'm sorry for my poor sentence structure. I'm not really sure what GMT900 or GMT800 means sorry I'm not that educated on the truck or stereo system. I'm almost positive it's not a base model because it has the mp3 plug in and cd player stuff like that. I thought that it had Serius XM because of the CAT button. Yes I have OnStar and it is currently active.

GMT900 is my truck 07-11

GMT800 is the older body style 99-07

If you have the mp3 plug then I'm guessing you have GMT900. The LS model is the bare one, LT has poor windows and door locks, and LTZ is the loaded model.

Im not an expert on the XM, but I think you have it and I would try another dealer. Maybe someone can tell you for sure.

Oh and the only thing my dealer said was its not compatible after he ran the vin. My question is basically if i buy another stock radio that has xm will it work or do i need a new tower on top of the roof as well?

I've got a GMT900 then and it's an LT. When i press CAT it says "XM only feature." I called up XM and I can't get my Radio ID number i don't understand it at all.

sounds like you don't have the XM receiver in the vehicle, do you have the XM antenna on the roof?

ebbthirtyn9ne · January 21, 2011

yes i have that on the roof

And that would be a onstar antenna, I have a W/T I have that same antenna, but no XM, dealer said I'd need a new radio and some programming hardly worth it when a Sirius unit I bought was only 80$

do you have the XM receiver behind the glove box?

If you have the XM module, then when you select the XM band... you will get the XM advertisement on Channel 1.

XM is not part of the radio, but you must have an XM compatible radio for it to work. the XM module is located behind the glove box. To check do this: open and empty the glove box. push up on the black tab inside the box that stops the door from opening any farther. swing down the door and look for the aluminum box mounted behind the door. Also, if you have xm, you should be able to get the XM channel that has the advertising on it.
