UPDATE..The re-boot worked. The Good news. The bad news...The SB side is dead. No touch screen, radar etc. but it's on. I do believe that the HD is going and is corrupted and for sure the int batts are dead. NOW, we will see if NB and SR (Brunswick extt warr) will do to make me happy. Clearly the SR Nav system has issues, I liked it, but now that its failing, I have more issues. Probably will replace with RM C120's and have a custom made binnicle IF SR gives me incentives. Stand by...
