This charting unit came with our boat
and worked well for a couple of years. After replacing it with a new Lowrance HDS unit it was relegated to a backup role. After a few months of not using it it started to turn itself off shortly after I started the unit. I decided to pull the unit from the boat
and after checking all the connections the same thing happens. At first it starts up and runs for a while before shutting down but eventually just shuts itself down almost immediately.
Anything to be done?
