I have an edge 130 plus and use the courses/ navigation feature regularly. In every course I've created the device fails to recognize about 40% of the turns. As in, I get to a 4 way intersection where I'm supposed to turn right and the "distance to next" still displays some distance, and there's no warning that there's a turn until I go straight through the intersection and the device tells me I'm off course. It happens on every single ride, seemingly randomly. It'll miss one or two turns in a row, then correctly identify one, then go back to missing them. I mostly create courses using Strava and push them to Garmin connect, but also create them with Garmin connect directly. This issue has happened all over the US and in Europe.
Garmin support was pretty mystified and asked me to send them pictures of the issue happening (what exactly they were looking for I'm not sure, the device NOT doing anything?)
Has anyone else encountered this issue, or know how garmin flags turns? I'm pretty sick of constantly having to turn around to get back to a missed turn...
