A320 COM/NAV Panel

  • So I hate using the FMC in VR and I would much rather use the COM/NAV panel to set my frequency/course with a couple of buttons on my HOTAS setup. Unfortunately when I press the NAV button on the panel the com frequencies disappear and instead of the NAV frequency and course I get a bunch of zeroes. Does the NAV function on the panel even work? Am I missing something?
