I am unable to get my external Garmin GNC 250 XL to drive the GRT Autopilot system. Does anyone have a GNC 150, 155, 250 or 300 XL hooked to their GRT EFIS and use it to drive the autopilot? If so, please contact me at the listed Email . I have some questions about settings. Or leave a reply on how it works and what is required in the setup communication in the GRT EFIS Menu.
Thank you.
