<![CDATA[How do I tune Nav2 on the PMS GTN 750]]>For some reason I can’t seem to access the nav2 radio on the pms750. I seem to recall pressing the bottom right tuning button in would let you toggle between nav1 & 2. That’s not working here. I have the paid version of the pms 750 installed and activated with the 650 selected as secondary.

I do not recall that I did change anything inside the settings.
Maybe worth trying if the Solution provided by @MiRexer does not work for any reason.

Like Nick said pushing the button switches between com and nav on each unit.

If there is some other mechanism to modify the frequencies normally displayed on the GTN 650, then I am not familiar with it.
