Facebook Launched A New Way to Send a Location in Messenger , Now you can choose to explicitly send a map of your location or another particular place as a separate message.

To get started, just tap the More icon or the location pin at the bottom of your screen. If you want to tell a friend which restaurant to meet you at, search for the restaurant and send a map of where it is. If you’re running late, send a map of where you are to your friend to let him or her know how far away you are.

With this update, you have full control over when and how you share your location information. You only send a location when you tap on the location pin and then choose to send it as a separate message. You can also share a location—like a meeting spot—even if you’re not there.

Sending a location is completely optional. Nothing is changing about how we receive your location information:

• As always, Messenger doesn’t get any location information from your device unless you enable location services for the app.
• Messenger does not get location information from your device in the background—only each time you select a location and tap Send when you use the Messenger app. We are not requesting any new permissions for your information.
