I have a 383c which I have setup in a small 13ft runabout. It works fantastic. However I now also have an 18ft offshore boat which has a dedicated depth sounder but no GPS.
Can I disable the sounder/transducer and just have the GPS? I have disconnected the transducer and tried turning the sounder on, but on start up the sounder looks for the transducer.
Can I bridge the necessary terminals through respective resistors or devices?
