(I'm posting here because i can't post in L-1011 forums)
So i wanted to use the RXP GTN 750 with the L-1011 since i know you can use the F1 GTN but for some reason the plane doesn't follow my route. I switch it to ONS and turn on VLOC on the GTN but it still doesn't work. I've tried VLOC with all three modes, (VOR, NAV, ONS) and i tried GPS with all three modes but still the plane isn't following the route. Is it that the L-1011 is not compatible for some reason with the RXP GTN? (I'm using the Prepar3D v4 CS L-1011 II btw)
