GNS430 only shows "XPlane 12"

[Mik75]

Hi there.

I just bought this fantastic plane and already did one flight. I own the Reality XP GTN 750, but not their 650. So, the XP default GNS430 shows up in the panel. But in the 3D cockpit, the display only shows the XP12 Logo. When clicked, the pop up 2D panel is fully operational. Is that the intended behaviour?

I'm running XP12.4 beta5

Thanks a lot in advance.

And another problem: Just wanted to do another flight. But the RXP GTN says "rebooting" and doesn´t react to the Avionics bus switch...
