Interesting, 530, on 3.20 firmware. Can't charge beyond 96%, any ideas. The unit has been reset twice, used various charging blocks and always the Garmin lead!! Shows the 
symbol, suggesting it's charging, but only to that point . Tried with unit off and on, same problem?!!
deckys - This will be fixed in a upcoming software release that is planned for July.
I noticed the same issue...powering down the device and connecting the USB cable helped to charge the Edge to 100%. Must be a bug in 3.20.
deckys - I will definitely look into this.
It forces the power to be reset, so it could fix the battery gauge.
