Thanks for the info-I found a Nexus expert down in Florida (recommended by Henry at Layline) and he sent me a new Transducer which I put in yesterday with success. All systems(Wind, Depth, and Speed/Temp) are now working save for the GPS Nav portion which has a disconnected Magellan receiver of some type and questionable wiring coming out of the server..I'm thinking of just investing in a new color handheld (Garmin GPSMAP76CX) that I can keep in the cockpit...
