Can I use Siri to remember a parking spot? Can I use Siri to remember a particular GPS location, then later navigate back to it? It seems like it should be possible but I don't know what the voice directive would be.

I occasionally use a car-share program that only offers two-way rentals. In other words, I have to return the car to the exact spot I picked it up at. It would be helpful if I could use Siri to mark the location where I picked up the car, so that later I could get turn-by-turn navigation directions back to that parking spot.

Yes, you can use Siri for this.

Simply say "Siri, remember where I parked my car."

Siri will drop a pin at the GPS location you're at.  You can use Maps to go back to this location.



As long as the parking location is marked, you can launch the stock Maps app on your iPhone and easily get walking directions to your parked car. This way, you’ll never have that lost look on your face ever again.



When you want to delete this parking spot, say "Siri, forget where I parked my car."  This will make Siri delete the pin.
