I have repeated this description here for those users who use the search option properly.
There is currently no user manual for the new Intelligent Navigation (NI) modes. DJI say follow the onscreen instructions, but to help you:
Access the IN modes by first taking off and being in the air. Then switch the P-A-F switch to F. This will display a IN selection dialog.
POI: Select Point of Interest (POI) mode. Fly the aircraft over the POI at a safe height to designate your subject. Move away to the orbit radius you want and adjust you height and camera viewpoint. Select the orbit speed (2-4m/s in best) and then tap Apply. Confirm the RTH safety height (clear of the height of your POI) and off you go.
Waypoints: Select Waypoints (WP) mode. Fly to your first waypoint and set the height and direction. Tap Insert WP or press the RC C1 button. Fly to the next point and so on until you have plotted the route you wish to fly. Tap done. You can tab the tiny little star to add the route to favourites to repeat it as many times as you wish. The last 3 routes are autosaved. You have a couple of choices on which way the aircraft will point, what it does at the end (hover or RTH) and the speed (max 5 m/s). Tap Apply and set the RTH safe height. Then off it goes.
Course Lock: The Course Lock (CL) sets the stick inputs relative to the direction the aircraft is pointing when the Apply is pressed. Ensure the aircraft is turned to point the way you want to fly.
Home Lock: The Home Lock (HL) uses the stick inputs in relation to the Home Point (HP). Pulling the right stick down moves the aircraft towards the HP, and pushing it away moves the aircraft away from the HP. Similarly, the left and right stick inputs moves the aircraft left and right from the perspective of the HP. The aircraft must be at least 5m from the HP before this mode can be activated. Note: the left/right movements will not maintain a constant distance from the HP, it flies a curving tangent.
The Follow Me mode is not available to Inspire 1 users.
