Hummingbird 580 not turning on - Kayak Fishing Adventures on Big Water’s Edge

Getting 12.47 on the voltmeter same at the terminal connectors and the at the head unit power attachment .9. There is a 2 fuse on the power line. So the unit has power. I'm guessing it's just the head unit. I tried to take it apart to see inside but I don't have a hex bolt that size and it's stripped just enough so my Allen doesn't turn it. Anybody have a lead on a compatible head unit?
