Plug in GPS/AP Unit for XP 11?

[Treetops45 1,082]

In P3D v4.1 I use a small plug in AP/GPS unit from WeFly Works in aircraft that don't come with AP or GPS. Primarily older aircraft.

It toggles as a pop up & among several things it does,  I can set Vs & Alt, & the GPS picks up a flight plan & the aircraft follows it, levelling of at the Alt I have set.

This allows me to set up a longish flight, depart, & then come back later for the interesting part, the landing. 

Is there an equivalent plug in for XP 11?
