I am having a problem with the RealSimGear GNS 430. I got everything connected and good to go with RealityXP, except none of the buttons work. I have tried reinstalling C++, Arduino software, etc. I know that the buttons are working because on the RealSimGear Interface, it shows they are being pressed. It seems like the RSG and RXP are not really communicating. Contacted support, no answer yet. Thank you!
