Here is the GNS.ini file to implement the 530/430 into the new TOGA Simulations MU-2 Marquise v2 panel. I have also set up both units to link to their respective VOR 1/2 and enabled crossfill in the RXP settings. You may want to adjust these to your personal preference. Enjoy!
Airfoillabs C172 - GNS 430 Panel Config
My first attempt at doing one myself as I couldn't find one for this model. Puts the GNS 430 screen in the 3D cockpit on the AFL 430 screen. I also enabled 'Use simulator GPS commands" and everything is working great!
