Hello,
You can easily switch between the functions of the FMS knob, to also allow you for NAV frequency adjustments, by using the middle mouse button anywhere over the FMS knob as well as the invisible clickspot located to the left side of the FMS knob.
This is described in detail, with screenshots in the TDS GTNXi XPlane PDF manual, page 31. Of course this applies to both the GTN750XI and GTN650Xi.
