Head unit wiring help

[silvrmax04]

I ordered a PAC OS-2BOSE and received a OS2-GM32...does anyone know if these are one in the same just an updated model number. I sent it back with a note that they pulled the wrong item and received another of the same again.
From what I am gathering it is not compatible with my truck. Does anyone have any info on this? I have a crew cab. bose system, onstar. Wanting to install a new head unit that I already have its a ddx419.

It should work? Do you have steering wheel controls?

Yes I do. I ordered a separate kit for that OS1-X I believe? On the PAC website it says that the BOSE that I originally ordered is discontinued and there is another model #. I ordered that one and should be here today.
