The first thing to do to get the CIVA-INS to work is to rename the panel.cfg (something like panel-BAK.cfg), then rename the CIVA_panel.cfg to panel.cfg. Once FSX is started with the CS707, if you are in the VC, press F10 to go to the 2D cockpit (it is just a window with the SimIcons 2D panel) to initialize the INS in the 707. There are instructions on how to move this from [Window00] to [Vcockpit01] in the panel.cfg in the Topic that Barnes pointed out to you.
