I am currently havin the same issue
Anyone find a solution to this? I just installed a brand new 4iiii Podium and it paired and calibrated perfectly with my 520 but on the data screen fir 3s power is blank the entire ride? Not sure what I’m doing wrong...
Like others above, I have the same issue with an installed 4iiii Precision. Data records after the ride, but does not display while riding, which is about as satisfying as riding without a power meter. I'm ready to go to Wahoo. Does Garmin actually look at these forums, or are we on our own? Garmin guidance would be helpful.
