While on a course today (course created with Garmin Connect), the Edge 540 repeatedly told me to turn onto roads that are not part of the course. Not during the whole ride, enough sections to make it unreliable to follow turn-by-turn. The unit seems to not be lost - it had me on the right road in the right spot along the road. But the turn instructions are bogus. No idea why, the course looks fine in Garmin Connect. This has happened more than once with other courses. OS ver is 26.18. Is there some strange setting that is recalculating the route? Thanks.
