is this one peace has anyone had this off before could I put a sirius antenna in it were the xm is.

 

I was told the XM antenna will plug in and work in the Sirius box. All you do is break the yellow clip off end of the XM antenna wire. But after reading several posts in the GM Sirius forums the SR-GM1 box will not work in the 06 Monte with XM which is what I was waiting for. If you know something different please let me know

 

it works but the lan wire to the radio is to short I would have to pull a seat out not willing to do that no one has a longer one for it.
