I have 2 speed sensors 1 for each bike.
Today I noticed that one of them is on Sw2.2 how do i update?
Spd sensor1: Model9, Man1, Sw 2.20
Spd sensor2: Model9, Man1, Sw 2.30
More to the point ... does it mater?
Do you know what the differences in the software versions are?
I don't know if the speed sensor falls in to this category, but resent software builds on the Edge 1000 and FR920 have added the ability to update some sensors from the device.
Currently I know it supports Vector and some models of Garmin heart rate monitors. Not sure about any other sensor types.
I think the comments more reflect surprise that you found that there are two software versions. I haven't see any comments at all concerning software versions of the sensor. Where did you find the version info? I would be surprised if that has anything to do with the xt920 problems. What are the problems?
