- The radar is openable. ( It uses the "Bomb Bay", you need the Simple Trainer to open it. )
- You need to use 'Next Vehicle Weapon' to select "flashlight" weapon ( just like select any other weapon when you in the vehicle ) to control the radar rotate horizontally
- The default weapon is the radar ("flashlight"), so you need to select any other weapon except "flashlight" to make the radar stable instead of rotating with the camera when you drive



You can look the pic in this file or watch this demo vid if you don't understand how to control the radar:
