If you are using the GTN 750, you may find that the EHSI can indicate VOR1 mode, while the autopilot indicates GPS mode.

 

I find this confusing..

 

So, to force the two to stay in synch, I've added the following code to an Update section in the EHSIVC gauge.

 

You can put it anywhere where an Update section is active in the panel.

<!-- Synch GPS/NAV modes -->

(A:GPS DRIVES NAV1,BOOL)  if{

  (L:EFIS550_Menu_DC1004_MenuNavSrcSel, enum) 0 != if{ 0 (>L:EFIS550_Menu_DC1004_MenuNavSrcSel, enum) } }

                          els{

(L:EFIS550_Menu_DC1004_MenuNavSrcSel, enum) 0 == if{ 1 (>L:EFIS550_Menu_DC1004_MenuNavSrcSel, enum) } }

Thanks! I just have to put it inside any gauge I want?

Correct, but inside an Update section.

 

You can add a dedicated gauge if you like..
