The reason for my concerns as to future support - I am in the middle of a panel upgrade for my RV8.
It is semi panel mounted via Air Gizmos mount. The autopilot requires NMEA output in a serial bus.
If the 740 is not going to be upgraded or replaced I am reluctant to continue down this path. Brand "G" in the Airgizmos mount is a drop in at this point.
Again, can anyone tell me what the NMEA interface would be for a tablet?
