At one time in the past before my PC crashed I had a PTO (Midway,Henderson,ect) GPS gauge in several of my Aircraft panels that I could turn on and was fun to use. Does anyone know what I have to do to make the GPS gauge show up again? On some of the aircraft I do have an "ON/OFF" icon for the GPS, but when I hit it to turn it "on" just gives me a black rectangle standing on it's end. Any help would be welcome. Thanks
