It would be very useful to pilots (and anyone else with a GPS) if you could see the exact direction and distance of your waypoint on the GPS screen.
On higher difficulties you can't see your HUD waypoint and the helicopter waypoint instruments are missing/non-functional
There is no reason why a GPS should not be able to replicate such functionality and this would be a more immersive way to keep track of your waypoint than the game HUD marker {F23996}
