May 9, 2025May 9 Hello, a summary of how the GNS530 / GNS430 are programmed in MSFS2024 / MSFS2020. The message is that their functioning is not consistent: sometimes GNS530 is NAV1, sometimes NAV2; sometimes the GNSs can be switched between GPS/VLOC, sometimes not; sometimes they are connected to a gauge, sometimes not. The differences depend on the panel (modern, classic with GNS) and which sim (MSFS2024, MSFS2020). Legend: NAV1 / NAV2 column: shows whether the GNS unit appears as NAV1 or NAV2 radio GPS / VLOC column: shows whether the GNS unit can be swapped between GPS / VLOC (both) or is locked to VLOC (VLOC only) or actuates on a different GNS unit linked to gauge column: shows to which gauge the GNS unit is connected The weird thing is that in MSFS2024, the GNS430 unit can sometimes be swapped between both GPS / VLOC modes but sometimes is locked to VLOC mode only. I conducted a number of tests but was not able to isolate what causes the unit to lock on VLOC only. Will update this thread if I find the cause. Edited May 9, 2025May 9 by apollon01
