Some aircraft in FSX come without an autopilot, or just come with a basic AP system consisting of altitude and heading hold. This is often cumbersome on longer flights as adjustments need to be made often 'in flight'. The best autopilots are those which will follow a flight plan via the GPS coordinates set out in the Garmin instrument and activated via the NAV/GPS switch. ....... It's a sim after all, so why not cheat a bit ?

I came across this older thread by 'bkeske' over at flightsim.com which outlines a simple way of installing a Garmin 295 GPS, the Maule GPS/NAV switch, and the Bendix-King autopilot (all three are FSX default BTW) inside an aircraft which lacks the AP functionality.

Posting it here, hoping it may of use to some.
