Went fishing yesterday and my unit turned on and worked fine. Then powered the unit down for a couple of hours while boat was parked at the dock and then when I went back out to fish some more the unit wouldn't turn on. Checked all the fuses and made sure that there was power going to the unit. Didn't have a multimeter with me, just a tester that showed if there was power or not. There was power at the power wire and then also power at the cradle. Not sure if its something to do with the cradle or if its something with the unit?
