I have the IFly 740B and a Trutrak 385 Vizion autopilot. TheA/P does not detect the GPS signsl from the IFly 740B. Nor does the D10A see a GPS sigal from the IFly. The A/P head has been sent back t the factory and was bench tested to see if it was working correctly. It was but still and is still not able to get any GPS information form the 740B.
Has anyone got the 740 to talk to the Trutrak A/P?

Yes, Mine works just fine...when it works, and to be fair it works most of the time. Problem is thtat sometimes the Tru Trak just will not say it sees any GPS info and when it gets in those moods, no matter how long I wait. the TruTrak does not get the info even for a 4 hour flight, unless I cycle the power to the 740. Then most of the time the GPS info apparently gets sent out. It does not matter if I cycle the power to the TruTrak, it will never see the GPS info, the cycling must be done by the 740 to work. Since I only have the one device hooked to the NMEA output and since I only have the xmit wire connected to the TruTrak, it is not being confused or conflicted, or otherwise. And also since it DOES work usually after restarting the 740, obviously the baud rate, etc is correct. Once connected and working on a flight it NEVER loses the GPS link. I can fly coupled to the autopilot for hours, no issues.
