Hi everyone. My problem is the following, I wanted to update a GPS garmin nuvi 760 I connected it to the PC and turned on the screen as it normally does, the problem is that after that the screen went out, I did not recognize it anymore the PC and I can not turn it on , not even disconnected, and when put to load nothing appears on the screen. I already tried to charge it with the car, with a source and with the usb of the pc and nothing, it does not react.
