Hi,
I recently lost the heart rate monitor and soft strap that originally came with my 910XT. It synced up fine and also with my Edge 800.
I bought a replacement monitor and strap but can't get either unit to recognize it. When I go into settings and in the heart rate section I select the ANT+ and search for heart rate monitor, the page reverts back to the previous page without searching. Seems strange that both units do this.
Directly beneath the "search" option, there is a option to view the monitor ID. When I select this option it shows that there is 0. Are the units still recognizing the previous monitor and somehow I have to remove that monitor from the unit memory before adding my replacement one? The replacement strap is new so the battery is hardly expired already?
