Autopilot not following GPS

[dizzyflores]

Hello,
I've been having a problem with the autopilot not following the GPS.
I'm flying the latest Turbo Otter on FSX:SE using GTN 750/650 v 2.06.

So what happens is sometimes the autopilot will start to intercept the GPS track in Heading mode with NAV armed. It'll switch to NAV and start the turn to the track then half way thru it'll level the wings and not follow the track. But the autopilot will stay in NAV mode. CDI is in GPS.

Also somepoint during the trip the autopilot will still be in NAV but wont make a turn to follow the course in the gps.

Hi,
This autopilot works different than default. You must position the HDG bug properly. Please read the KAP 140 manual included in the package.

Thanks!

You also need to ensure the instruments are powered by turning on the AC and DC power switches on the lower part of the center console. The relevant instruments can appear to be properly powered and NAV/GPS will not work unless these switches are on.
