For the ride today I've created two separate courses on Garmin Connect site since it was easier to place course points on separate courses than same one due to overlapping.
First course had several course points at few summits and they were al displaying correctly in "Distance to Next" field on Navigation screen, and all the distances were showing correctly on Course Points screen.
When I was near the end (about 50m before end mark of the first course) of the first course I stopped and was ready to go back, 830 went to pause mode, I switched to navigation screen, stopped current course and wanted to load return course with new course points. There was no problem selecting the course, course details screen showed up, I tapped on Ride button, but nothing happened. There was no prompt like "You are near the beginning of the course, would you like to start" or "Would you like to navigate to course start". It just stayed on course detail screen. I tapped Ride button few more times with same results. After that I pressed back button and it got me to Navigation screen where I saw that new course was loaded and in "Distance to next" field it said 10m. I've checked Course point screen and they were showing correct distances to created points, so I decided to move on. 830 changed from pause to active mode, but as I was moving along the route, "Distance to next" was not updating to next course points and kept showing 10m, same as Course points screen kept showing 11km till first defined course point. I've passed that point, but there was no change, next point was about 1km further and I've stopped little after (20m or so) it to get some water. 830 went to auto pause, and back to active a few min later when I start moving again. Now there was a change in "Distance to next" field and it showed correct distance to next course point from the point where I stopped, but again it was not updating. Same thing happened after stopping at next point. It changed to distance to next, but did not update it when I was back on the move again.
I've checked settings for Route Recalculation in Activity Profile and it was set to Automatic, so that's not the cause.
My previous unit was 510 and this kind of route change was working without problems. Did anyone else experienced similar issues?? This seem like a software bug to me.
Also I'd like to know why did they remove option to switch off Virtual Partner in Course Detail settings and is there any way to disable it.
