Can someone please tell me how to tune COM 2 and NAV 2 in the GTN 750?  I can see that you can transmit and monitor 2 but I can’t see how to select the tuner.

First, welcome.  I see that you have been a member here for a couple of years but now making your first post. This is a great place to share and benefit from our collective experiences.

Perhaps explain your need a bit more?  Are you using (2) GTN's and desiring to have one on COM1/NAV1 and the other on COM2/NAV2?  

You can find the RXP Users Manual in your Windows Start menu under R / RealityXP.  The manual will explain how to access the GTN's Configuration Panel by pressing and holding the shift key, then Right-Clicking the top edge of the GTN device with your mouse.  That will open the configuration panel.  Once open you can scroll the available settings an in those you can find the COM/NAV settings.

As a fellow RXP user I highly recommend that you read through the manual, perhaps more than once as it is detailed and it will take some time to digest.  It should however provide answers as you read it, which will get you further along faster than waiting for responses here.

Thanks for your response.  I was assuming that it worked something like the G1000 that has provision to tune both COM and NAV 1 and 2 from the same panel but it appears that this is not the case.
