Tips for Pairing ANT+ Accessories with Your Garmin 

Device

• Verify that the ANT+ accessory is compatible with your 

Garmin device.

• Before you pair the ANT+ accessory with your Garmin 

device, move 10 m (32.9 ft.) away from other ANT+ 

accessories.

• Bring the Garmin device within range 3 m (10 ft.) of the ANT+ 

accessory.

• After you pair the first time, your Garmin device automatically 

recognizes the ANT+ accessory each time it is activated. This 

process occurs automatically when you turn on the Garmin 

device and only takes a few seconds when the accessories 

are activated and functioning correctly.

• When paired, your Garmin device receives data from only 

your accessory, and you can go near other accessories.
