So I’ve update the Cown Sim 222B and 206B3 (bought them via CowanSims own webshop. not marketplace) to their latest versions : v2.2 and v.2.1
So both have the option to use the PMS50 GTN750 to be used as as imstruments :
I can switch between the “normal” instruments and the PMS50 GTN750 not a problem but they just won’t start up : screens stay black all the time.
Now CowanSim heli’s had problems with nav instruments in the past, but to my knowledge they solved it.
So does anyone have a idea how I can fix this aka make the GTN750 working ?
Do you have the latest version of PMS GTN750 ( 2.2.31)? Also worth checking if you have any other garmin GPS mods causing a conflict. I’m sure I saw someone reporting a black GTN though on another aircraft and it was just an out of date GTN that was the issue. Also saw today someone on the Taog’s Huey thread reporting a black map screen on the GTN today too although it still booted. Maybe there is some common issue? Just guessing though.

If i remember correctly they use 3 gps, the GTN 750, Default 503 and another GTNXI i think its is. Make sure you’re on the right one i think the PMS one is the top position on the switch they also do take a few seconds before they start to initialise.
also persistence doesn’t work and they go back to 503 after a restart and you have to toggle the switch down then back up
