Little map bottom left of screen-how to interpret? – July 12, 2022 at 03:56AM

Can anyone point me to a clear explanation (perhaps a You Tube) of the facilities provided by the little map bottom left of my iPhone (sure it has a proper name) linked of course to the basic MA2 RC. Am using the latest Firmware on Fly and the RC. Even though I have made over 300 flights (mix of Spark and MA2) I don’t feel I have good understanding of this.
