I seldom use turn by turn when following routes, so I have turn by turn switched off. When I first received the 820 (software 3.1) I had a lot of frustrating experiences until I found how to switch off turn by turn when following routes (turning guidance off under navigation -> saved courses -> options). After that, the 820 behaved as my previous Edge 800 and Edge touring plus: the "distance to the next" is the distance to next waypoint, the distance to dst is the distance to the end. When going off-course, the "distance to dst" got frozen on the last course point, and the "distance to the next" gave the distance to the closest on-route point (and the compasss pointed to the closest route point). This is great when you go off course and want to track the course direction and how far you are from it.
I was happy again until upgrading to 3.2. After the upgrade, following on-course works ok, but the device seems to get crazy when going of course: it draws a straight thick pink line (I believe to the destination) and the distance to the next and distance to dst become equal -- I believe they report the direct distance to the the end of the course (or maybe the start, I am not sure). Moreover, it often gets lost when returning to the course and I have to reload the course from scratch to get proper distances to the next and to dst. This seldom or happened to me with my old 800 (the distance to the next got sometimes lost when going off-course, but the distance to dst was always ok).
Anyone else with this problem? Is there any setting that I am missing?
There is a similar thread here, but with turn by turn on, which is not my case.
