It has taken me a while to be able to supply a screen shot as requested. I had to do an uninstall of everything because I tried upgrading FSX with SP2 without doing uninstalls, and I got bad results
Anyway, I finally got everything working again, and here is what my screen looks like while enroute (according to my preferences

)
I have found that once I have my flight plan setup, I don't use the FMS anymore. As you can see, my screen is rather busy. I fly on the VATSIM network, and you can see I have several screens open pertaining to that scenario.
Is the gauge showing engine data the EICAS? In any case, that area between the ND gauge and the "open" buttons is where I have the EHSI control opening (though I have to open it through the menu at present; for some reason the button is not working).
I keep the GPS_500 open for better situational awareness. Also, because I don't understand how to use the FMS or MCU correctly to setup my approach vectors, I use the GPS to select my runway with a vectors to final choice, then manually fly to an appropriate point from which I can let the autopilot take over on GPS mode to get lined up, then switch to NAV mode within about 15nm, and prepare for my final.
Most of my difficulties at this point stem from my ignorance of properly using these gauges. I'm learning, but my approach still seems rather "clunky".
So there it is. This is my current setup. Suggestions on improving it are most welcome.
P.S. Ernie, I'll post separately with some questions about the EFIS CNTRL not working. I assume you'll want to see my panel.cfg?
