I recently changed my GPS from an AVMAP EKP IV to a Garmin 400W. I am feeding the data to the D10A using the RS232 input. After a few minutes in flight with NAVSRCE selected from the GPS, the autopilot goes off track and starts a left turn. The HSI stills seems to function normally and the data on the HSI display appears to be running and accurate.
The Garmin is set on Aviation and outputting on the first RS232 Channel.
Interesting that I had this same problem with my AVMAP a few years ago but I went into the NMEA statements selection and deselected many of them, leaving only the ones listed in the Install Manual active and that seemed to solve the problem.
Not sure if this is the same issue but the Garmin does not allow you to select the statements.
Any advise?
