Fred,
There's a lot I don't (and probably won't ever) know about my units, but the first time I powered one up after dimming the screen, I thought my unit was bad because I couldn't see any display at all... Lesson learned is all I can say.... I'm going to put this out there for all the guys (and gals), there's some things about this night fishing that I have learned over the years (and I know Mike has as well) that we don't even think about now, but if someone has a question, we may have already found a solution or work around and there's no need to re-invent the wheel... With that being said, someone else may have found a neat trick that we may want to look at as well... Everyone has their own way of looking at things, and a different set of eyes can often see a better solution... I'm always willing to help where I can, and if someone can improve on something in a discussion I'm involved in, jump in, we may all benefit from it... There's a wealth of knowledge on this forum, and I for one like to see people helping others solve problems or give tips to make our sport more enjoyable....

Absolutely Doc. I was a little luckier on the discovery though. I was home, with the boat in the yard. I tried to turn it on to check the chart from the previous night's trip. I wanted to see the trail of what ground I had covered. It was about 2 pm, and the boat was in the sun. After troubleshooting online I went back outside and tried it again. By that time the boat was in the shadow of the house, and I could faintly see the intro screen. DDDUUUUUHHHHH! This is the first time I've told anyone about it.
