Rick ChurchillOn two separate websites I have read of the feature Show Parked Location which identifies on Apple Maps the position where your car was parked. (usually I can't find mine because I'm on the wrong floor in a multi-storey car park and this feature would probably not help)
...however I read that it (the feature not the car) is found in Settings > Maps and by scrolling down to YOUR CAR but there is no such text on my iPhone 11 running IOS 14.2.
The websites are WikiHow dated July 2020 and RawInfoPages dated November 2020 so they are both recent.
Where is it hiding?
