AI just went belly up and have a loaner in the plane now. Have looked at both the G-5 and the AV-30-C.  Prices are comparable for the Garmin as an AI only unit, but the UAvionics does a lot more (up to 12 functions, connects to legacy S-Tec 30 autopilots,like mine, etc). Interested in finding out how people made the final decision on which to buy and how you are liking your choice.  Installation costs for either unit? Most any comments would be helpful.   Thanks in
