I am very unlucky.., this piece of junk tarnishes the name of Garmin..! It works whenever it wants and unfortunately, it doesn't want to work often.., when it does work, it's only for a short time and then it disconnects.. and then I just leave it alone.., I'm tired of changing settings and doing resets (by removing the battery). I have gone through 2 divorces.., but my relationship with Sensor2 is infinitely more problematic and in the end.., it can't even make a decent pasta dish..! I hope you are luckier..!
