A friend has a GNS430 with an HSI in his RV8A.
He's starting to train for IFR in it.

When he switches from VLOC to GPS tracking the HSI does not switch to track
the GPS waypoint.
It continues to track the VOR or Localizer.
Is this a wiring issue?

It doesn't sound like wiring to me?? There are a number of
'configuration' menus that make everything work. I would talk to a
quailfied avionics shop, Garmin or the company that made the HSI and
see what they think?

Which make and model HSI? Is this one of the HSIs that is covered in
the GNS400 Series Installation Manual?

The HSI is a Century NSD-1000(Electric)
Is there a unique config in the 430 for this HSI?

My old copy of the Garmin Installation Manual shows how to wire the
NSD-1000 HSI, and there is no mention of any special issues. I
looked at the list of configuration menu items, and didn't see any
that were obviously relevant to your problem.

My installation manual shows a possible cause. The HSI lateral and
vertical deviations are supposed to be wired to pins on connector
4001. These pins send either VLOC or GPS deviations, depending on
what is selected. But, there are VLOC only lateral and vertical
deviation pins on connector 4006. I can't find a description of what
comes out of those pins if the GNS 430 is selected to GPS, but it is
possible that they would continue to send VLOC data. Maybe your
friend's HSI is connected to those pins rather than the ones on
connector 4001.

Who did the wiring?
