GTN 750 reverts to the departure airport

[redripper 0]

I'm using the GTN 750 with PFC xplane 9.7 FAA version.  I notice when I use the 750 that after  few minutes of flight the system resets back to the original departure airport. This does not happen when i use same A/C using GNS 530 v2, only GTN 750.  Any thoughts as to why?

 

thanks

Hi,

do you mean X-Plane 'slews' back to departure (your reference to 'system'), or the GTN only (i.e. the GPS position is no longer the same as in X-Plane)?

while flying for a bit, all systems are a go - no issues, frame rate are way above 35f/s, GTN working fine.  all of a sudden I'm back on the runway where i started from.  It appears Xplane is resetting.  this only happens with the GTN not the GNS.

 

Not sure why.
