^^^ This ^^^There is one button and one button/knob. I will simulate it for you right now. Hold the left one and it turns off or you can adjust the backlight (with the twisty right one), twist the right knob and it adjusts the baro pressure. Push the second one and turn to get to your altitude preselect other installer enabled functions, in our case zeroing out the horizon bar to set for level flight. Hold both buttons and you go into install mode which is where the magic happens.
That will be $19.99 but you can just send me a $20.

Very funny, but the "magic" you refer to has more than a dozen options and configurations. Watch this:
Sorry, I am not sending $19.99 for that
A simulator would be nice to for those wanting to understand the GFC500 annunciations. Sometimes the books just suck.
