Unable to couple GPS to Autopilot

Recommended Posts

Hey guys! 

Well I bought the RXP GTN 750 some days ago and already had some fun with it in some other planes.
But I really like the Carenado Phenom 100/300 but unfortunately the build-in GPS system is crap so i decided to try and implement the RXP....

After some time I got to this point---> *Click*

Everything is funktional execpt the buttons on the bezle and as described in the title the Autopilot still follows the standard GPS thingy.

So now to my question: As far as I can see, it seems that I have to change the GPS source or disable the standard one, but HOW do I do that?!

I already tried various setting in the RealityXP.GTN.ini file but it didnt work. I will post it below so you guys can have a view on  that too.

 

RealityXP.GTN.ini:


[GTN_750_1]

usealtmouse = false
; enable touch beyond screen bounds if true (2D only), clip if false (GTN native).
extendtouch = true
; auto-resize dimension (width,height)
refsize = 
; left mouse button on the screen toggles popup window by ident (ex: GPS_PANEL or 225) (requires SHIFT+left mouse button).
popleft = 
; right mouse button on the screen toggles popup window by ident (ex: GPS_PANEL or 225).
popright = 
; adjust brightness (0 to 100)
brightness.bezel = 100
; offset brightness (-100 to +100)
brightness.screen = 0

 

Hopefully someone can help me 😕

Because I really want a businessjet with a good GPS system...

 

Let me know if you need any information or files!!!

 

Thanks for ANY help!

Try right clicking on the memory card slot on the GTN.. it should switch the "active navigation" device.

Hey thank you for your answer! It seems like this is a F1 specific thing because there is no such clickspot in my GTN 😕

I tried it with the 2D Panel and in the Virtual Cockpit without the NO_BEZEL option.

Is there no way to change it by hand somehow?

Hi,

I think this is the most needed setting. This will make sure the FSX A/P system is using GPS signal when in GPS mode, and VLOC signal when in VLOC mode. Otherwise, you'd have to find a way to toggle NAV/GPS source on the panel independetly of the GTN CDI mode (GPS/VLOC).
