My edge 830 had been nothing but a pain in my rear, every time i take it out there is some sort of malfunction. I have a cadence sensor as well as a speed sensor on my main bike, and just aspeed sensor on my other bike. It now will not connect to my phone and I've tried restarting both devices, uninstalling connect and reinstalling it. If this thing takes an hour to dry up every ride then it's basically worthless.... Latest ride it sensed cadence but no speed or distance..... Come on Garmin this is an expensive piece of tech, it should work!!
