My EDGE 540 Solar device has become unusable after this update. I can't navigate around the device at all with the buttons.
I managed to start a ride yesterday after the update and immediately noticed that the page up button was not working. Then when I went to I went to stop the ride the stop ride button was not working. I managed to end it by plugging into the computer and have now noticed that it is a general problem with the buttons of the device.
I have tried a full reset by holding the lap and start stop button and then pressing the on/off button but it still doesn't work.
Why release an "update" like this and give users no way of reverting to the old software?
