Connecting to the Smartphone Link App on Your Apple Device
Before you can connect to the Smartphone Link app, you must pair and connect your Garmin DriveAssist™ device with your phone.
If you did not connect to the Smartphone Link app during the pairing process, you can connect to it for additional Bluetooth® features. The Smartphone Link app communicates with your phone using Bluetooth technology. The first time you connect to the Smartphone Link app on an Apple® device, you must enter a Bluetooth security code.
