I'm starting a new thread, since I think others might be having issues with the GTN SW updates.
I posted this one to an older thread, but didn't get any replies. Sorry for the repeat. But this probably warrants a new thread. I saw some other discussions on this in other threads. But no direct answers to my specific issues.
I have a GTX 345 connected to a GTN 650. No other avionics are connected. So, I don't have a heading source, or an altitude source connected to the GTN650.
I have a Gillham Altitude source connected to the GTX. Both units have the latest software.
GTN v6.50
GTX v2.12
I'm having a little trouble with the configuration.
The GTN gives me two warning messages (that I can't clear)
1) NAV ANGLE: NAV Angles are referenced to True North
2) VNAV: Unavailable: Barometric altitude lost.
I have Altitude Source and Heading Source disabled on the GTN.
Any suggestions would be helpful.
Questions:
1) How do I get rid of the warning messages?
Also, it seems that I might want a pressure altitude going to the GTN for VNAV support:
2) Can the GTX send the pressure altitude source to the GTN?
3) - OR- Do I need to connect a pressure altitude source to the GTN to get VNAV support?
4) If I connect the Pressure Altitude to the GTN, do I need it also connected to the GTX,
5) or can the GTN feed the GTX the pressure altitude source?
