This is just me but turn by turn I a bit annoying. I really don’t need a computer beeping at me every 10 seconds about an upcoming turn. I’m out there to enjoy a ride.
All I really want to know is if I’m off course or not which the bolt does pretty well. Load up the course in Strava. It’ll sync to your bolt and the only beep when you’re off course. Minimal sounds.
You have to watch the map of course, but I suppose I’m the weird one and that I don’t like my car GPS Sound on either.
