@rmeier - excellent find.  I don't think I've ever loaded a default flightplan into the GTN 650, so I missed that step when running through possible fixes.  Hope it's what the OP needs.

Thank you very much for your help, guys!

I'll try those steps and i'll tell you about the results.

@jovejunior:

I think I was able to replicate your issue with the flight plan tracking.

I tried to enlarge the photo you provided in an earlier post...I couldn't tell if the green "GPS" logo was illuminated in the lower left quadrant of the GPS/VOR/LOC/GS Indicator.

After re-reading p15 of the F1 User Manual, I could reproduce your issue with the aircraft following the flight plan vs the 360 degree heading.

On the GTN 650 unit, if you hover your mouse over what looks like a blue memory card on the left side of the unit, it should display the Active Navigation Source. A right click on your mouse will change the source between the default P3D GPS and the F1 GTN. (You'll notice GPS logo will light up/turn off as you toggle between the two modes.)

I could repeatedly toggle the aircraft between the flight plan and 360 degree heading during my test flight this morning.

Hope this works for you!

Hello guys! After a long time, I bring the news for you! 😂

Those steps did not work with me, the GTN continued following the CRS360. Buuut, when I deleted and redownloaded the GTN from F1 website, all issue was solved! I think that it happened due to incompability betwwen the GTN old version and the P3D newest version.
