You don't happen to have the gupdate file aswell? i can't seem to get this one to actually install for some reason. i'm putting it in the /garmin folder, but it simply starts up with no update happening.
Yes i managed to figure it out thanks to google translate and the file provided by Nicolas, seems to be better at keeping a charge now, but i am going to let it drain completely and then recharge it over night and then do a factory reset just to make sure it has every chance to be calibrated.
I will keep this revision in my backup folder aswell, good to have a version people seem to be happy with just in case. :)
