I have an older Garmin Forerunner 910xt which I hadn't used for a few years and realised I had lost the original ant stick so I purchased a new one. Garmin express can see the ant stick but cannot find the device (ie Forerunner910xt) and I get the error message of "We found an ANT sticj=k but didn't find a device". I have turned pairing on on the watch. Any ideas of how to pair my watch and ANT stick?
