As far as I know, this software only shows where you are. No
routes/waypoints. No autopilot control.


Are there nav packages that control autopilots? All the autopilots I've
seen had their own processors and processed a magnetic heading input.


If your nav package only receives a position and heading from the GPS and
this nav package maintains a route, it can calculate the cross track error
(XTE) and send that info to an autopilot.
