I have an older Nobeltec Nav program on a laptop. It is currently connected to a GP 32 through a serial port on the laptop. I purchased a GP-330B to replace the old unit. It came with a 6m NMEA 2000 cable, apparently this is not the right cable for this application. What cable and or accessories do I need to to make this connection.
