Garmin's is literally "oh shit the pilot passed out!" and an entirely inexperienced passenger can push a single button, ending up with the plane stopped on the nearest appropriate runway with the engine off. The autoland system in airliners requires a lot of setup by the pilots and continuous monitoring all the way down, plus working ILS (instrument landing system) equipment at the airport.
Yeah, I don't know what button he would have told you to push, but it definitely wouldn't have landed the plane. I don't think there were even automatic wing-leveling systems that far back.
