I've noticed a difference in Track flown (see G3X screenshot in flight) VS Track displayed in the flyGarmin playback.

In flight the AutoPilot was ON with TRK selected 360°. The playback displays a track of 006°

This discrepancy applies to all other directions as well.

First guess is that one system is using true North and the other magnetic. The difference would be most notable on that track you were on.

It's always + 5° or 6° difference, same for all 4 directions (N,E,S,W)
