I am wanting to switch my xm tuner to sirius and believe I can do this with a sirius sir-gm tuner, but I need to know exact location of xm tuner in my 2009 colorado, can anyone help?

 

its above the glove compartment

 

I have had glove box out only thing I found was at passenger side of instrument panel and I believe that was something for my on star not sure tho, I'll try looking again thanks

 

Onstar is to the right of the glove compartment.
The D.R.R.(Digital Radio Reciever)(XM Module), is above the glove compartment. They are both silver boxes, but the D.R.R. is smaller and only has two connectors on it, one being a greenish coloured coax for the antenna.





<LI type=1>Unfold the service panel located above the I/P compartment door.
