I recently bought an 830 to be a bit more reliable than having a phone connected to a battery pack running komoot. Last weekend to try it out I transferred a route from Komoot to it. The transfer was fine and the map and distances looked correct on the Garmin. It asked if I wanted to navigate to the start of the course, I said no as the start is somewhere along my street.
The route was 60km along bike paths and roads, all of which are well used and appear on all maps. Throughout my trip, the Garmin showed me on the route, but the navigation prompt (at the top where it should tell you what is upcoming) just said 'head northwest on road'. At first I thought it had just not found me on the route, but after 20 odd km it still showed the same. However, if I went off route (roadworks etc), it then gave me directions back to the route which worked fine, but back on the route it reverted to 'head northwest on road'. About 40km into the route, a few directions did pop up, then it said off course, allow recalculation? I said yes and it said....'head northwest on road'. A few km later it asked for recalculation and I said no, it showed me on the route just fine, but told me to, yes, 'head northwest on road'. Then, for the last 10km or so, the directions worked fine. However, I have no idea why as before and after them working I was on the route just fine.
For nearly the entire route I was right on track, and for nearly the entire trip I just saw the one useless navigation prompt. Did I do something wrong, is there some way to instruct it that I am on the route and start navigating along it now?
I have done the same route numerous times with the Komoot app and only ever had very minor issues with directions.
