GTN750 and Carenado C90 (Searching made it worse!)

So I bought the GTN750 due to it being "integrated" into a few Carenado planes. I own the C90, B200, and PC12. So far, only the PC12 has the proper integration. My question is this, how can I get it to snap into the C90 like advertised? It works as a popup on a second screen however, I would like it integrated into the dash the right way. I searched and someone mentioned deleting the RXP.INI and starting over (that did not work), I also copied a few settings from other threads (didn't work), and now I'm here posting and hoping for an answer.

Thanks!
