I've been pulling my hair out for hours trying to figure this out, and have wound up here. I'm using P3D V2 and running the Carenado Embraer Phenom 100 aircraft. I want to map the MFD and PFD keys to my keyboard. I have a registered copy of FSUIPC (I'm a novice user, just got it today), but whenever I click on a key in the MFD or PFD of the G1000, it says .. Key not programmed -- passed on to FS. When I click on the button in the G1000 using the mouse, it works fine. I can't figure out how to program a keyboard key to it though. Important to note, the pre-made G1000 controls in both P3D and FSUIPC under "Control sent when keys pressed" do not seem to function for the Carenado Prodigy G1000 in this aircraft. Can anyone offer some advice on how to fix this? Thanks!
