Am flying the DC-3 Retro panel (example Emerald Harbor)  with the Duckworth enhancement addon. Having a problem with the auto pilot. It engages the Heading and the Altitude buttons but will not engage the NAV button and sometimes it will not engage the Approach button. 

Any suggestions?

Thanks

You have to engage the blue hydraulic lever to the lower right side of your pilot seat first. That enables the autopilot to work.

Yes I know that and I do it. Must be something else.

By the way. Other planes such as the Cessna 172 with stem gauges uses this same auto pilot control panel with the same function buttons and everything works properly on it.

Thanks
