After sw update yesterday my edge 1030 plus will not power on. Tried to hold power button for 10 seconds, did not work, tried holding both lap/start buttons then power button, "GARMIN" flashes on screen, there is a beep and the unit is just stuck in this continuous cycle. only way to power off is to hold power button until the beeps stop and the screen fades away. happening to anyone else or any ideas welcome. Thanks.
