CDI scaling with GNS430 as the nav source
-
With the nav source set to the GNS430, the CDI on the EHSI and the little CDI on the EADI seem permanently fixed at 10NM scale. They don't change scale to match the GNS. I confirmed that it is not simply the "10NM" annunciations...the CDI deflections do not match the GNS.

I haven't confirmed this, but looking at the code, here are two ideas: Did you have the autopilot in approach mode, or NAV mode? If the AP was in approach mode, then it might mean that the GNS is not properly setting the GPS APPROACH MODE variable. I've seen these GPS variables become considerably stuck in MSFS 2024. Which version of the sim are you running?

NAV mode. I did not attempt an RNAV approach because of the scaling issue. I can try it out a bit later.I will note that the GNS's enroute CDI mode is 5NM, so I wouldn't expect the EFIS to indicate a 10NM scale ever. That said, I'm sure there are some nuances to the way the Garmin is integrated with the Starship avionics.
MSFS 2020. (Sorry, I should have thought to include that.)

More testing. I tried to shoot an approach with LPV available. When engaging APR mode on the AP, the CDI scaled down to a fixed 2NM scale and EFIS displayed a glideslope. However that G/S never budged from full-up deflection, and the AP never descended.Also, the TOGA button & binding don't function when I have the GNS selected as the nav source, seems to be the case in all modes of flight. As soon as I switch back to the FMS, it functions normally.
