Not sure what I did differently but the HRM just started working the next time I tried it. Although the screw threads are now damaged and I haven't had a chance to call Garmin about options yet with all the holiday business and multiple ski trips. I did notice that the speed and cadence sensors don't like to just work without either forcing them to connect once I start a work out or having to wait a long time. The cadence sensor took 15 min to connect yesterday and the speed has taken up to two minutes. Kind of annoying. I am still using my cateye strada wireless so I wonder if the signals are interfering with the Garmin signals.
