[SOLVED] BUG: Just Flight PA-28R Turbo Arrow III (MSFS) AP unable to capture VOR

[leclettico]

As per object and video.
MSFS and Just Flight PA-28R Turbo Arrow III/IV (MSFS) are up to date.
I have to redirect the aircraft with the HDG heading and switch to follow the course offered by VOR signal

[SOLVING]

The manual isn't properly clear (or was my fault), but even in NAV or OMNI coupler mode the HDG switch must be turned on.
