My RV-6A (I didn't build it) has a Trio EZ Pilot autopilot, but it's not connected to any GPS input. So it's only able to be in wing leveling mode. I have an NMEA0183 GPS receiver similar to this one. According to Trio's manual, the parameters should match (4800 baud, NMEA, 8-N-1, etc.)
After I connect it, the autopilot detects some input (it automatically switches to course mode), but keeps showing "NO GPS". I also have an FP-5L fuel gauge. In MPG mode it shows "on", which means it connects to the GPS receiver, but cannot get the ground speed data. All these behaviors are the same regardless of being on the ground or flying.
I connected the GPS receiver to a computer and read its output. Everything looks alright. Position, ground speed, course, etc. appear in sentences $GPRMC, $GPGLL, $GPVTG and such. But it doesn't have magnetic variation data. Maybe this is the problem?
Has anyone had success wiring a similar GPS receiver to Trio EZ Pilot? Am I doing something wrong or is it just fundamentally incompatible? Thanks in advance!
