After MSFS SU10 update, the NAV/GPS button on the C172 (above VOR1) won’t toggle the status between NAV and GPS on the VORs as well as on the GNS530/430.

To change the status of NAV and GPS on the VORs, one has to press the CDI buttons on the GNS530 and 430 in the virtual cockpit respectively.

The issue seems true to the C172 only. Have tested the NAV/GPS function on other aircraft and they all work fine.

Too bad, many times the C172 is always the one messed up by new updates.
