Finding true north

Paul Wilson <plw@...>

Hello All,

Does anyone know if the GTO hand controller supports a routine for
locating true north? I read an saa posting many moons ago that stated
there was a built-in routine for doing this, and it worked in the
daytime. I can't find the posting that described it, and I don't see
any documentation about it in the manual.

Maybe the feature never existed? Maybe it's been obsoleted? Any
insights would be greatly appreciated!
