Check the wire drawings and see if the 430 passes the info/data to the G3X and if the configuration settings are set for that kind of matchup. It might be different?
I am probably overlooking something, but when I hand-fly a practice approach (ILS or RNAV), using dual cue guidance on the G3X and the G5, I don’t get left/right, up/down guidance like I would in my airplane with a Garmin 430 and a conventional nav head. What am I missing?
Did you arm the APP, the FD is basically a function of the AP just without the servos engaged (AP off).
(I'm assuming it will fly the approach with the AP engaged).

That's curious. Not having the flight director is one thing, but if you have the LOC/GS tuned and the you have switched from GPS to LOK, shouldn't you see the deviations anyway (without the flight director)?
I'll be interested in how the OP's refly goes. Were you sure you were in LOC on the navigator and not GPS?
It could be confusing in this discussion to differentiate between 'Activating Approach (GTN)' and 'Arming Approach (Autopilot)'.
You'll always need to activate the approach on the IFR Navigator. If you want the VBar or Dual Cue (Flight Director), that is a function of the autopilot system. You just need the Flight Director (FD) activated, which is possible without having the autopilot engaged or Approach Mode (APR) armed.
Either way with an Activated Approach (GTN/GNS), you'll be receiving vertical and lateral guidance, its just a matter if you have the Flight Director on or off.
I had the flight director on and activated the approach in the 650, but I did not activate “apr” on the autopilot, because I was hand-flying and did not think I needed to tell the autopilot to activate. Are you saying it should have worked the way I did it?
