Bought a HRM Pro to see how the chest strap works for me with regards to estimating pace and distance on the treadmill.
Connected it to my watch, as well as Garmin Connect, and updated the firmware through Garmin Connect. It only gave me version 8.10, and both the watch and Garmin Connect keeps insisting that this is the up to date version. Can't find any files to try a manual update through Garmin Express either.
Obviously a bit of a bummer, as it means I've shelled out for a new strap that now has no extra functionality compared to my five year old and fully functional HRM-Run.
Suggestions?
