Com/Nav push button not available

[rfra]

Newly installed TDS GTNXi in XPlane11 using the default XPlane C172SP and just using the pop out window.

There is no way to click on the Com/Nav frequency button to switch it over to the NAV frequencies, the only functions exposed are the left/right frequency adjustment values.  This makes it unusable for VOR navigation or for switching to the ILS frequency when intercepting the final approach course.

Note this is not in any way integrated into the aircraft and is only running in its own pop out window.  Doesnt matter if I use the 650 or 750, both behave the same.

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.
