I've been using my Garmin 500 with my wireless powertap and GSC-10 speed/cadence sensor since May 2010. Use it on every ride with no problem till yesterday.
About 45 minutes into the ride, suddenly both cadence and power stopped being read/recorded on my 500. Speed, distance, time, elevation, etc kept recording as the GPS was not interrupted. When I downloaded the file, I could see that the cadence and power stopped recording at the exact same time. And it wasn't during a stop or auto-pause situation...we were going 20 mph at the time and I was not coasting.
Ok...so here's what I've tried so far.
From the settings, it shows that no ANT+ power meter or speed/cadence is detected.
Here's what I've tried so far.
Power on and off...no luck
Rescan for both devices while within range, no other devices near, and while crank is turning...no luck
Complete reset of my 500 and downloaded and installed the newest garmin 500 update as per Garmin's instructions. Then rescanned for devices...still no luck.
I reported my last test to Garmin via email and am awaiting a response. My question is just if anyone experience something like this. The computer works fine, just with the exception of reading anything ANT+. I don't have my HR strap anymore, so I couldn't test that. I suppose it could be the battery in the devices...but what are the chances they both
(speed/cadence and powertap
) die at the same time. I tried pushing that little white button on the speed/cadence sensor, and it does light up...so battery looks fine on that device.
