Okay...let's try this again.

It was nice that mark767 offered a CIVA INS solution but there seem to be too many questions and some confusion regarding Shift+2 to bring up the CIVA icons.

Here is code for a Dual-CIVA using a non-modified / stock panel.cfg, copy and paste the yellow highlighted sections where nessesary:

NOTE: Place gauge39=../civa/INS!Config, 0, 0, 0, 0, CSB727 in [VCockpit01] -OR- gauge01=../civa/INS!Config, 0, 0, 0, 0, CSB727 in [Window00] - NOT both places!
