I just bought my Duo and installed on my bike, the Garmin 520 paired with no problem, went through the calibration "0" process again with no issue. the lights on the pedal are orange and everything looks good for launch! issue is that there isn't any data coming ot the head unit (520). I deleted the pedals to start over, paired with no issue and nothing. Any thoughts here, I reached out to both Garmin who had no experience with this, and Assioma who has not responded after several attempts.
