quote:CS-- I am dealing with the same problem with my LMS-525C. I talked to Lowrance Service and they had me try a disconnect-reconnect. Didnt work. Just send it back with Bill of sale was the instruction. Before doing that I took the GPS module up to Tyee marine in Campbell river . The Module is working fine. Wires seem to be fine too-- but before I send it back to Montreal, I will try to find someone who has another extension cable and see if that is the problem. If its not that-- then the only other thing would be the connector on the Lowrance. But if I had followed thier advice first off-- I would have got the module back with a note that there was noting wrong with it. I HATE electronics
