I gotta say I am disappointed in Garmin and probably buying a Wahoo. According to my Garmin profile, the 830 I am having trouble with is my fourth Garmin, including a 305, a 500, a 520+ and now the 830. They all had some issues, but this inane customer support takes the cake. Like many I am getting massively innacurate grade and elevation data, making it all but useless. I have done the partial reset that saved my routes, I have done the full reset that wiped it all clean, I have deleted various folders as described in some forum suggestions, and I have cleaned it under warm water, all to no avail. I still get negative gradients when climbing, elevation changes when stopped (dropped 300 feet below our minimum geographical and geological elevation during a potty break). When I do an elevation correction on Strava, and these are for routes I've ridden countless times, it's like the Garmin was on another planet recording data on some entirely different event. Yes, it gets distance, speed and similar data right. But I want data on gradient and elevation for training purposes.
Plus, a luck would have it, my 830 was registered in March of 2022 so is now out of warranty by a few months. Not only does the exchange price of $140 plus tax stink, but they require me to send the unit in before shipping the replacement. Making it worse, in talking with the support person, in essence, he said modern electronics are meant to last only a year or two anyway, so this sort of failure is just the way it goes with modern electronics. Seriously, I should be okay with a $400 item not doing what I bought it for after about 15 months. What kind of BS is that? I guess they think their customers are idiots. Anyway, I'm trying one last cleaning of the port providing access to the barometer, etc and if that doesn't work, it's Wahoo for me.
