same here for me. updated to current firmware didnt solve the problem for me, and i went from the base 1.0 version!
here's the thing guys, idk how the 9 volt adapter connects to the pcIII, i've never seen one, much less use one so i'm completely clueless and unless i'm an idiot, i cannot find a reference for one on the pcIII website. i dont even know where it would connect to the pcIII for that matter.
what i mean is, i cannot figure out how the 9 volt adapter would connect to the pcIII when it's connected to the bike. this is what baffles me.
any help, pictures, etc?
