I have a Garmin 205w. Last night I connected it to my computer and disconnected it. Afterwards, I was unable to turn it on. When I pressed the power button, the logo shows up for a few seconds and disappeared. And then I pressed top left corner of screen and tried to power on, no use, then pressed bottom right corner of screen and tried to power on, but it didn’t. Then I connected it to web updater, and couldn’t find device. Can someone suggest me how to fix this problem?
