Situational Awareness

Your Forerunner device can be used with the Varia Vision

device, Varia

 smart bike lights, and rearview radar to improve 

situational awareness. See the owner's manual for your Varia 

device for more information.

NOTE: 

You may need to update the Forerunner software before 

pairing Varia devices (

Updating the Software Using Garmin 

Express

, page 26

).

tempe

The tempe is an ANT+ wireless temperature sensor. You can 

attach the sensor to a secure strap or loop where it is exposed 

to ambient air, and therefore, provides a consistent source of 

accurate temperature data. You must pair the tempe with your 

device to display temperature data from the tempe.
