Garmin 800. Cadence data is recorded and average and max are visible in activities and the graph appears when I transfer to iPhone app but on main data page on garmin connect the cadence graph box is totally blank (not even any axes) as soon as I save or edit the data or try to disable elevation correction which now seems to be enabled by default and impossible to disable??!!. How do I disable it, on the device if possible? Driving me mad any help appreciated.
thanks
Mike
