Princess Cancer Pants
I'm hoping this is what I'm dealing with. Since it just got COLD and a little snowy here and the kid was home for teacher inservice I had no choice but to drag the bike and trainer into the house. Got set up, in the saddle, Garmin on, started pedaling, hit start...flaky cadence, no distance or speed #s.
Reset the cadence/speed sensor and it flashed red/green, like it should. But still is not paired with the Garmin (I think I got it to briefly pair, but then the little cadence sensor symbol in the accessories settings had the flashing x over it, again). Tried re-pairing. No dice. Hrmmmm... Sounds like this button battery is good for about a year. Bike will be a year in exactly 1 week.
Any other thoughts?
MTA: we had a fresh battery, so I tried that...no change. When I'm attempting to pair the devices I get the red flash every time the pedal/cadence magnet crosses the sensor, but no green light from the wheel. The entire shebang appears to need to be re-paired every time I'm turning the Garmin off, too. Huh?

Figured it out...somehow the spoke magnet got bumped out of place by about a mm. Probably happened sometime this Summer, but went unnoticed as the GPS was measuring speed and distance outdoors.
