I'm still in the planning stages however I like to plan ahead even though I know avionics change with the wind. I'm planning on using all garmin stuff, G3X touch, GTN etc. but I can't decide on the configuration. I will have a PFD on the left and an MFD on the right but in the center I will either have a 2nd MFD with a GTN650 below it or no 2nd MFD and put a larger GTN750 in the center. Seems like it's done both ways frequently and I just wanted to hear from people that have similar setups. This will be a family traveling machine, IFR capable going 3-500 miles. Thanks for any input!
