Hello,
I have 30 ride files with my garmin 830 and garmin vector 3 pedals. 12 out of 30 files have data dropouts, or data with straight lines. This is beyond a grievance. I updated my garmin immediately after buying it, forgot the original version software number, but have updated twice in the last 40 days. I also troubleshot the pedals with baby oil (lol >1k product needs baby oil to improve function) which has not improved a thing. I have calibrated and re-calibrated and I am about to the point of never buying another garmin product again, for life.
To rectify this problem you can replace my pedals and my headunit. In return, you can have my data files to improve your product for other users.
