I know this is an old unit and discontinued, but I went to change my battery and when I insert the battery the light flashes a quick green and red light, but then nothing. It cannot be read by head unit or Garmin or anything. Has anybody else had this issue and found a solution, or id it just dead?
Perhaps the batteries are low, buy a new set of high end batteries and see what happens.
Another Powertap C1 user here. Never had any issues with it whatsoever.
Good luck.
