I have several cycling activities uploaded to my Garmin Connect account, and when I first played them back there were no issues. However, months later when I try to replay one of my routes, the playback begins at a point about two-thirds of the way into the ride. When it's done playing, the indicator jumps back to the starting point on the map, but if I hit play again it again jumps to that same 2/3 point. I even tried playing one of my connections' rides and had the same problem. The entire route is highlighted on the map, but it refuses to start the playback from the beginning. Operating system is Windows 7 Pro. Any ideas?
