ELEMNT, BOLT, and ROAM can pair with rear view radar systems (like the Wahoo TRACKR RADAR, Garmin Varia, or Trek Carback) following the same pairing procedure as any other Bluetooth or ANT+ sensor.
For information on using radar units with ELEMNT ACE, see Use ANT+ Rear View Radar sensors with ELEMNT ACE.
Requirements
- ELEMNT, BOLT, or ROAM updated to current firmware.
- ROAM v2 or BOLT v2 to control light modes.
- If using the first generation Garmin Varia, it must be also be updated to the newest firmware.
