In case anyone is interested in the answer to the question I posed above about where vertical guidance from the GNX 375 is displayed, here is the reply I received from Garmin:
Leonard,
If you are using a G3X or G5, the vertical deviation will be shown next to the Altitude tape:
Picture attached.
Let us know if you have any other questions.

This clarifies that the vertical guidance is produced by the GPS unit, but not displayed on it. It is sent to the G5 or G3X or to a CDI for display. I?m presuming it?s also made available to the autopilot for coupled approaches.
Hopefully this will help, although I?m probably the last person to figure this out!
