After you have Find my Friends set up, using it with Siri is as easy as 1, 2, 3. First, activate Siri and ask her, “Where’s [name]?”
You can follow up with the command: “Take me to [friend’s name].” You will then be sent to Google Maps for directions.
The simple command of “Call” will call the friend you’ve requested the location for. During testing, we didn’t find the ability to message through this command.
