I have two G3 iEFIS panels. I upgraded the firmware on both now the touchscreen does not work on one of them. The soft buttons still work. I cannot find anything in the menu structure to re-enable the touchscreen. Anyone have any ideas?

I want to use Pin 23 from the iBox Analog/Digital inputs connector to illuminate a light on the panel for EFIS alerts. Where does the ground go? To the instrument panel ground or to one of the "G" pins on the connector.
