AP Behavior in the R172 G1000 NXi

After activating the flightplan using the GARMIN Screen in the Cessna 172 G1000 NXi, when I press the AP button after takeoff, the aircraft starts circling and makes no attempt to intercaprt and follow the SIMBRIEF plan. The Aircraft becomes uncontrol-able and i have to re-start the flight.
Any suggestions will be appreciated.

Hello, can you send us a screenshot of your setup in the sim?

Here are some screenshots. As you can see, the flight plan has been activated, but when I press the AP button, the Cessna R172 does not follow the plan.
Why???




Hello, it seems from the pictures that you are not in GPS mode, you are in ROL
Have a look at the attached photos. Ensure that you select NAV. That should do it


Thank you… but now I need help to activate the flight plan. Do you have a video showing how to do this?
