Sigma BC 12.12 The Total Distance shows 45.079 and it is stuck there. All other functions seemed to work fine. How can I get the Tot Distance to work again? Respectfuly, Bill Z

Sigma 12.12 won't reset data. Instead get a message to " resync reset". How do I do this?? Thanks Steve Rogers

I just changed the battery an am having trouble resetting the wheel size. How do I get to that setting? How do I change the setrting? Your visual manual is the worst manual I have ever received with a product. Once this thing dies your manual will be a big reason I look at getting a different brand of bike computer!

I replaced the battery in my Sigma BC 12.12 and it won't function now. Current speed blinks 0.0 when I attach it to mount. No distance or average speed or anything.
