When I am on a course, if I am going to a dead end, most of the time the garmin device will say off course, then say make a u-turn, then finally it will adjust and be on route again. This getting back on course may take a while to fix itself even though I am on the course. The navigation works much better than in the past but still needs enhancements to clean it up. I also think that garmin needs to add pausing the course if you go off course like it is added to the 1030 plus. This may prevent these messages when stopping for a break.
