This is my 2nd Forerunner 645 with Music, the first 1 was only just months old when this Blue Triangle came on during an up date. Thanks to my bike shop a replacement I was giving 18/04/19
Monday 20/01/2020 the Blue Triangle came back on, the watch was acting funny all day, with having to restart a number of times. I love the watch Pleas help
