Stopped for a 10 min snack/stretch break, I hit the stop button, Garmin powered off via timeout as expected. When resuming, the Garmin logged an *instant* 1,000ft+ ascent on the ride and elevation recorded an insta-blip of a nearly 2300ft drop! Ugh! Nothing unusual about the stop, weather, or action. Had to use map data to correct the ride. Anyone seen this? I never had this happen on my previous units. First road ride out w the 1040. Running v12.15
