GTN750Xi not starting up when launching MSFS2020 and C414AW
#1
Hi,

Had this problem before but it magically started working. However, the problem is back again.

I start msfs2020 and i see the splash screen for TDS GPS GTNXi when msfs2020 is loading.
I now launch the Cessna 414 AW selecting the TDS GTNXi 750 livery of the plane.
The C414 AW loads up and the GPS GTNXi screens are black. This is normal. 
I switch on the battery and the avionics switch and now i expect the GPS GTNXi 750 to start up but nothing happens. Both screens just stay black.

Before i tested again i have updated TDS as much as i can. Both the trainer and the msfs2020 part as well as the GPS manager. See picture.

I tried to load the PMS50 GTN750 livery and now the screens start but i could not use GPS for navigation. Only VOR navigation would work. In GPS mode, when i pressed NAV on the autopilot, nothing happened. Also , the maps screens were showing the background fine but the magenta route lines were flickering. In GPS mode, the needle on the HSI was vibrating. 

I also include a picture of the cockpit when i am using the GTNXi 750 and after i have switched on the battery and avionics.
Perhaps not interesting but when i switch on the avionics , the autopilot shows 3 red lights like it's doing a self test before they go out.

Best Regards / Jan
