How can you tell if the unit is charging ? On the bike .....it shows a green battery but no indication of it being charged as I ride 8 ?....hope this is not a daft question !

I would start with a low battery, then remove it from the bike after a decent ride, and check the battery indicator again. this should tell the tale.

on the 590 you can press and hold the battery icon and after about 5 seconds it brings up a page with loads of info on it

You can see if this screen if it is charging or on battery power

Try in on yours and see if it works
