I have a Lowrance Endura Out & Back that is just over a year old. Recently I have been having powering issues. It seems

As far as my Enudura Out & Back it is very frustrating since this instrument has been dependable up until this point. I use the unit for hikes in my area logging trails and waypoints. In the last couple of weeks I found I can start the unit getting running and it appears to be fine. If I shut it down it does not restart. This is with batteries, power from my truck, or connected to my computer. Over the past year this has never been an issue. It also has shut down on its own without even flashing red to show low power. It seems if I let it sit overnight it does restart. I have set it back to default. I am not sure of the different functions of power saving and if this is contributing in any way. Also, does the hand held GPS have any other battery within it. Please advise since now the weather (hopefully) is getting better I tend to increase my walks and go to more unfamiliar areas. If you need more information let me know since this situation is very frustrating since Lowrance only gives minimal information when purchased.
Thanks,
Ray Savickas

Relist: I still need help.
The problem was not resolved and adequate information was never forwarded, but yet the $30 has already been posted on my credit statement.

Still no resolution to my problem.
