NAV2 not working

[NZWX]

I'm using RealityXP 530 and 430 (both) config. NAV1 works fine, however selecting NAV2 on either Garmin unit is not reflected on CDI. However, NAV2 radio stack (with DME info, etc) correctly shows NAV2 navaid data at the same time. Quick radio (Shift+6) shows blank NAV2.

I figured that to resolve this issue before every flight I have to switch config (SHIFT+3) to "NO GPS", switch ON COM2/NAV2 radio stack, then switch config back to "530/430".

Is there a way to have NAV2 enabled by default for GPS configuration?
