I am installing an S-Tec 55X autopilot into a Cessna 206. The aircraft has a Garmin G1000 panel now. Can anyone tell me where, on the GIA63, I can get the ARINC-429 data needed for GPSS on the 55X. The data stream must contain the 121 and 312 labels to enable the S-Tec to track the flight path from the G1000 GPS receivers.
Thanks.
Glenn
