I have a Mooney Bravo. Has anyone installed a G3X with a GI275 that has a KFC 150 autopilot ? Our local avionics shop is telling me that it can't be done because the GI 275 would have to be the primary. The auto pilot is working great so I didn't want to change it out until it needs to be. Secondly I maybe installing the EIS with the G3X Thanks
