I upgraded my software yesterday on my 510 and all hell broke loose. I lost all my ride data, settings, bike profiles, etc. Additionally, I am now unable to create new settings on the device. For example, when I try to add a bike, the changes I make are not saved. The device thinks my bike weighs 4,817 pounds and will not allow me to change it. Nor can I change any of the other settings. Very frustrating!
