My track anomaly did not occur while simulating anything. I was simply recording my travels as I do every day, and when I got home one day to open my saved track record, I saw that I had warped through the very fabric of space and time to visit the coast of Africa. Several times. This very glitch has occurred on multiple occasions, and I have multiple track records which display the odd behavior. WHY does the Garmin briefly think it is near the coast of South Africa, for just a SINGLE track log recording point, then snap right back to it's true position?
