Though it already has the automatic parking location detection, it doesn’t really work always.
So when you park your car next time, open Google Maps and tap the blue dot, that is your location.
Then tap the “Save your parking” option to save your spot on the map.
You can also add notes, and edit the car location.
You can even share the location with your family or friends, so they can also go straight to the car-parked location.
