I was out on a ride today, noticed that the mph was fluctuating all over from 0.0mph to 30.0 to 5mphwhen my speed was constant.Thought it was the battery so when I got home changed it. and made sure the magnet was aligned.Still no luck any ideas of what could be wrong?

My speed keeps showing low. I have adjusted the magnet, I have made sure that my wheel size is correct. The Unit is new so I should not need a new battery. What do you recommend?

All of a sudden the computer stopped registering as I was riding. I changed the batteries, but that didn't help. The magnet and speed transmitter set-up had been working fine and I didn't change that. Any ideas?
