I’m trying to understand those errors. If I go off a route with the wahoo i just appear off the dotted line on the map and it then flashes once I get back on the planned route. The Garmin did the same but had rerouting ability which was an advantage if very unpredictable. To view the whole route I’d look on the app. I’ve never tried routing with headset only via the app. I’ve had a few occasions where it has lost signal under trees as I did with Garmin. I don’t like the USB port cover and the Garmin mount was better. I’ve had one occasion when it hasn’t uploaded automatically although Strava was down that day. It pairs quite well with the phone so I can see texts and Mrs Geo can follow me, on occasion this drops out, probably because of the phone signal.
