Hi - I have a classic. Put in a brand new battery, got the green flashing light, gamin head unit says connected, shows device details, but no power reading. I get cadence, but no power. Any ideas?
Update: just took the cover and the light is red. It was a brand new Renata CR2450N battery. What would discharge the battery so quickly?
