G3X/430/OBS

[Guy80b]

I have a G3X non touch with GNS 430W +GMC 507. When I want to use the OBS key on the 430 a pup-up window appear on the 430 screen since I changed the GSU 73 for GAD 29 and GEA 24. Before when I was selecting OBS on the 430 I was using G3X to select new course direction. How can I get rid of this pup-up and come back to the G3X to make the selection?
Thanks

I believe that pop up window goes away when you press in on the right hand knob. Personally, if you have a CDI indicator like a HSI or a VOR/GPS indicator head, I just roll the arrow to the desired OBS heading.

Thanks, I’ll try it on my next flight.

Based on past experience, this sounds like a problem with ARINC 429 configuration to me.
