Garmin recently announced their next-generation retrofit flight display, the G500 and G600 TXi. This all-new new avionics system is available in a variety of configurations and can function as a Primary Flight Display (PFD), Multifunction Flight Display (MFD), engine-monitoring system, or all of the above. The system only has a few buttons and knobs on the bezel, and is controlled primarily using the large touchscreen display.
