I'm running my Edge 510 on older software as it doesn't work with my Vector pedals on the newest. I want to use GE to sync my activities but foremost to sync new workouts to the unit (is there another way?), but GE updates my Edge's firmware every time I connect it. Yes, you can manually remove the UPDATE.GCD file but if you forget it, there's unwanted extra work restoring the old version and settings...
Is there a way to disable this automatic update?
