I had opened a ticket with X-Aviation and asked me to download an updated file to fix G500. see below
First, please re-download and re-install from the new download: https://www.x-aviation.com/catalog/account_history.phpThere's a new addition of code in the installer that may help with this.Also, as a cautionary measure, please be sure you do not have X-Plane running when you re-install the G500.Best Regards,Cameron
This seems to have fixed the error msg when adding the G500 to aircraft . But still the displays are blank. Please note that all battery switches and avionics powered on.
