Receiving Data From Your Handheld Device
Before you can receive data, you must enable broadcasting on your handheld device. See the owner's manual for your handheld device for more information.
Place your handheld device within 10 ft (3 m) of your Garmin DriveTrack™ device.
TIP: Your Garmin DriveTrack device receives data from one compatible handheld device at a time. Stay more than 10 ft (3 m) away from other handheld devices or disable broadcasting on handheld devices from which you do not want to receive data.
The devices connect and synchronise automatically. When your Garmin DriveTrack device receives data from a compatible handheld device, 
appears on the main menu.
