I've done everything suggested about fifty times. Wet the band, repositioned it, run the update on Garmin Express (I think it was already up to date anyway - v.8.0.0), soaked the band, went for a jog, tried outside, inside, in the basement.
My watch just refuses to detect the Premium Heart Rate Monitor.
I had just purchased the heart rate monitor, so I took it back to the shop. Annoyingly, they didn't replace it, instead they rang Garmin support, and the advice Garmin gave the shopkeeper was, "that is a common problem, just tell him to keep trying until it works". Seriously?
Do I have to do this "until it works" every time I want to use it, or just to pair in initially? Even if it did connect finally, how could I have any confidence in this?
Does anyone else have these problems?
