Hi All,

I've had a Garmin Edge 500 for almost a year now. Other than an occasional erroneous reading, or unexpected shut down, it has been very reliable . . . until now.

Friday morning I was playing around with my cleat position so I put the bike on the fluid trainer. For some reason it would not display the speed. It displayed the cadence just fine (through the GSC 10). Since I was going out of town that afternoon, I didn't have a chance to play around with it until today. I tried re-pairing the GSC 10 with the Edge 500, no change (i.e., cadence works, speed doesn't). I tried pushing the re-set button on the GSC 10 - I get the red light flash, the green light flash after pushing the re-set, and a red light when the crank arm/cadence sensor passes by, but no green light when the magnet on the wheel passes by.

I tried it on my other bike (with a different GSC 10 unit) and both cadence and speed seem to work fine (at least on the repair stand).

Any suggestions of what else to try? Is it time for a new GSC 10? Should I replace the battery? I'm open to ideas.

Thanks,
