I used the pack PAC adapter and use the Preset ABC switch on the radion panel to run BOTH a xm and a Ipod. I used the rear connection to the sattelite and spliced in the PAck adapter. Maybe I don't understand what you said and if so sorry, but that is what I did. GRIP
The reason why the Nissan is not listed maybe has to do with the fact that there is no CD changer connector at the back of the radio unit. The Bose and the CD unit are linked internally so you would have to do a little more work in providing the adapter with the proper signals.
