Hello,
I recently got the 830. I set everything up. While everything works, in one ride I'll get a few messages that say the power sensor is found even though the data was always there. I've read in other posts that doing a full reset, can stop this. I have also read that even after the full reset, the problem comes back. It's not a terrible thing. I just ignore it but it would be nice if there was a real fix. I don't think this is caused by the sensor. I recently replaced the battery in the stages crank power meter. The Garmin firmware is the newest version.
Any thoughts would be greatly appreciated
