I have successfully paired my heart rate monitor and my cadence sensor to my Garmin 910XT, however I cannot figure out for the life of me how to display my heart rate and cadence on the screen of the 910XT during my indoor/trainer rides.
Mode Settings (enter)Bike Settings (enter)Data Fields (enter)
(you can program up to four fields on up to four different screens. After you hit Data Fields you select which screen you want them on. I am assuming Screen 1)
Bike 1 (then select how many fields you want - I’ve got 4, enter)
Scroll up or down to the one you want to replace with Cadence then hit “Enter”
