I was doing a bit of early snooping for avionics today and went down to talk to a Garmin avionics dealer/installer. I told him that I wanted to build an IFR aircraft and was talking about the GTN certified nav/com. He told me that the EFIS displays would also likely need to be certified as well. Having certified EFIS's is obviously going to add a whole bundle of $$$ to the purchase. I would appreciate it if anybody can shed some light on this.
Thanks
