Having been delighted with my Edge 130 I upgraded to an Edge 130 Plus. I noticed a problem, namely that occasionally it would stop updating elevation, both in real time and on the final data. OK, I can correct height online but it's dispiriting slogging up a 100m 12% gradient to be told that you have gained no height and it's flat.
I investigated further and discovered that the problem ALWAYS occurs after switching off the device mid-ride, then switching back on. I carried out an experiment.
With the Edge 130 and 130Plus recording I did a quick up and down ride. Both devices were accurate, and consistent with each other. I switched both off and on again and repeated the up-and-down ride. The 130 gave a similar result to the first lap, but the 130Plus elevation started to lag, only updating after a minute or so. See graph below. The Edge130Plus is the red line
I showed this data to Garmin Tech Support who agreed that there was a problem and agreed to replace it with a refurbished unit, which arrived yesterday. And this one has EXACLTY the same problem. See graph below. The unit takes more than a minute to update elevation (on longer rides I've known it to fail to update for many minutes.
So now I await Garmin's response. I wonder whether anyone else has had this problem?
