Are there quality issues with the Bolt v2?
My first Bolt v2 would not give turn-by-turn direction cues for any gpx routes over about 120km. Wahoo Support couldn't identify the issue so it was replaced under warranty.
However, the new Bolt I received has exactly the same issue.
To add to this, the new bolt won't recognise gpx routes that I manually copy onto it using a USB cable. But this worked fine on my first Bolt. So this forces me to use ridewithgps with the Wahoo app, which isn't ideal for my route making workflow.
I might just give up and send this second one back for a refund and buy a Garmin instead.
