Got the battery from amazon and installed it. It perked up the snappiness of the functions maybe. But, still no reaction from either spinning the wheel with everything installed. Tried holding the sensor in my hand and using other magnets with zero results. This unit is probably 3-4 years old but was still in the original package and unopened. I doubt Bell would do anything due to the age of this unit.
Dam. I really only wanted to be able to read miles per hour, total miles, and to have a resettable tripmeter.
