Cessna_C172SP_G500 HDG out of alignment and NAV mode not tracking waypoints in flight plan

[cwjohan]

Just tried navigating in the Cessna C172SP G500 and had almost zero success navigating from CYVR Rwy 26L to CZBB Rwy 31 RNAV approach.

Four main problems:
1.)  It can track the heading via the HDG bug but it is out of alignment by maybe 100 degrees.
2.)  The S-Tec Like autopilot wasn't tracking waypoints in NAV mode.  Going direct to the first waypoint of the approach didn't work at all on the first try.  On the second try it did, but then messed up going to the second waypoint in the approach -- went the opposite direction instead.
3.)  The G500 flight plan panel wasn't showing the approach part of the flight plan.  Behaves a lot like the CRS is wrong.
4.)  In the log.txt one can see a bizillion messages resembling "2026-02-24 20:52:59 OpenGPWS[png.c:70]: Cannot open file F:\X-Plane 12\Resources\bitmaps\Earth Orbit Textures\+40-240-nrm.png: No such file or directory" from OpenGPWS.

So, there are some complications here, since there is a Laminar GNS 530 nav unit, a Laminar S-Tec Like autopilot, and a G500 that need to integrate, but it seems they are not sharing data or are sharing incorrectly.  Does navigation with this setup work for anyone?

The second log.txt below is "the second try" flight, which involved exiting X-Plane 12 and restarting again at CYVR.  Ended up landing at a different airport than my original destination of CZBB.
