A:Answer Hello,
While the nuvi 57LMT is not Bluetooth-enabled and you won't be able to do this through a Google service, it is possible to send a location from an Apple or Android Smartphone to a Garmin device using the Garmin Smartphone Link application.
For instructions on doing this, you can refer to the article below:
