Speed Sensor 2 - Software v4.0

Garmin, what is the reason for software version 4.0 for being pulled, is there another version being released soon?

  • I've been trying to do this update for 2 weeks and it keeps failing. I've even taken the sensors off my bike and put them on top of / underneath my Fenix 6 watch and it fails every time. I don't think it's ever got further than 31% but it usually falls over at 4%, 8% or 25%. The light on the sensor stops flashing

  • Thanks for the tips. I’d been trying to update speed sensor from a Fenix. Managed to get update thru following your advice - by turning Bluetooth off on the phone, and keeping the wheel spinning while the update completed from the Fenix.  You’d think Garmin would program the sensor to not go to sleep if it was in active comms.  Anyway will now see what V4.0 has in store.
