Just to add to this: on my last gravel ride, I downloaded the map file from RidewithGPS. The Bolt displayed the route on its map correctly. However, its cue sheet seemed off. The turn by turn directions were definitely wrong. I would get the turn notification a couple minutes after I arrived at the turn. This was within about 50 miles of a major metro area, so I didn't think that GPS was an issue. On a previous gravel ride in a small town, I got correct turn by turn notifications. I suspect it was an issue with RWGPS or with the way the ride organizer drew the map.
