MSFS 2020 Cessna Longitude

Did a flight and when I tried to set the coarse I clicked on the Nav Source button and it did nothing. Could not switch from GPS to NAV1. After a while it did change.  Also when I did an ILS approach, and switched over from GPS to NAV1  the plane didn't follow the approach. I was close to final, activated APP, went from GPS to NAV1, correct ILS freq was entered, Coarse was set and plane did not follow approach. Anyone else have this problem? Or any suggestions on why this is happening? Seems like I did everything right and everything was set. Thanks, Walt

If I remember correctly, you don't need to switch to Nav1, it will catch anyways.

Are you using Darkfly's Longitude mod with WT G-3000 mod? I have no problem with them.

Did you have Autopilot set to "On"?

Yes, Everything is set for the ISL, APP, NAV1,ILS Freq checked, CRS checked. this bad boy should be going in for a perfect landing. Yet, when I switch over to the VOR1, the plane decides to go sightseeing.

Really? That's interresting, because I did notice the glide slope showing up on the PFD while in GPS mode. I'll have to play with this. Thanks

Yes I have the WT G-3000, and don'tthink I'm having a problem with that.

Have you selected the correct nav source on the touch screen to your left? It's just below the pilot's side window.

Yes, I am doing everything correctly. Have done many many ILS approaches before  without any trouble. So can't figure out why I have this problem all of a sudden. 

Going to try another test flight now from KOXC to KBDL. Landing ILS Runway 33 108.55 Coarse 328. Lets see what happens.
