My Garmin Edge 830 is not displaying the segment screen when getting to the start point of the segment, the screen "blinks" which makes me think is because it knows I am at the start of the segment, but it doesn't show the segment screen. It does not happen with every segment, just with some of them. The segments have the "Enable Live Feedback" mark on, the activity profile I am using has the "Segments" mark on and the Segment screen activated, and my Garmin has the 5.51 software version. Any help would be apprecitated. Thanks!
