Just had a frustrating ride with my new Edge 830. I was following a generated course, and had voice navigation prompts enabled in the app. The display of the head unit showed current position / turn prompts, but for the second half of the ride, in my ear the phone was still telling me to do what I had done 30-60s earlier. The discrepancy was confusing enough to have to backtrack a few times.
My phone, a Galaxy s9, was in a fabric handlebar bag, inches from the Garmin, if that makes any difference.
Anyone experience this issue before? What's a good fix?
