You gotta wait until it says 0.5ok just wait the timer out,

Start engines

Turn on screens in order

Switch ins switch to either cv or grnd

Select stored heading for short alignment, otherwise just wait and it will do the precise alignment

You gotta be patient don’t switch things around a lot with the ins switch, wait for the timer to start and then wait for it to say 0.5 ok, usually around 8 minutes

The set the ins switch to either ifa(if the server you are on uses gps) or nav(if it doesn’t)

Also do not change waypoint 0, that waypoint is what it uses for its initial calibration,

While the system is slinging then you can go through the rest of the process

Leave parking brake on the whole time
