Map settings menu page has single item at top. From there scroll down all the way. Lat/Long/Altitude only displays when stopped.
Yes, I see it. When I go to Map --> Option and scroll down I see "Location & GPS Information" button but it only show address very close to my location the Latitude / Longitude and Satellites entries are empty when the car is parked inside garage. When I move the car out it shows GPS coordinates.
To save it as a waypoint, what I've been doing is first magnify the scale by pressing + a couple of times, then I press over the current location with a stylus, and it allows me to rename the destination and store it.
I used the coordinates to call an air strike on a tailgater using the SOS button. The voice refused to redirect the drones to my location. I guess they were to busy patrolling.
Those GPS coordinates are very handy. Typical examples, you are lost somewhere/car broke down etc. and want someone else to find you all you do is provide these coordinates to someone who has a GPS and they will locate you. You went to a friend house and his house is not located on the map yet and want GPS to memorize/mark this location, just click save button.
