In my case, for my C177RG 1971, cost installation 375 and Trutrak autopilot was around 15K. Amazing fun now. Had to install a new radio to resolve problems of interference, new antenna... Be aware about these consequences. The mechanic is not always going to predict them and tell you in advance.
Looking for 3 days on the Island in sept.
Any advise about hotels and b&b?
Would like to rent a cart or car.
I’m expecting windy conditions for landing.
