Per the manufacturer: The Flight Plan Sharing feature of the GI-275 will allow the Connext feature of the Multifunction Indicator (MFI) to serve as an access point for sharing of flight plan information from Garmin Pilot to an external navigator. However the GNS430W does not have this capability.
Q: Do you need an outside air temperature probe? And if you do, does it need to be the Garmin GTP 59?

Q: Will this integrate with my G1000 GPS position source and GFC700 A/P? Or would I have to install yet another antenna? Trying to get rid of my electric gyro backup AI.
The compatibility chart does not list the G1000 GPS or the GFC 700 to be compatible with P/N 11-17861.
