FurunoGP330B/0183 GPS Sensor w/10M NMEA0183 Cable

Great product, but when splicing the cable onto a preexisting GPS cable for a Furuno NavNet system (e.g, used for a GP320B), do not do a color-to-color splice except for the power conductors (red and black). The transmit lines from the 330 go to the receive lines on the existing cable and the receive lines from the 330 go the the transmit lines on the exsiting cable. And do not turn on any of the NMEA sentences (e.g. RMC, GGA, VTG, ZDA) from the NavNet back to the 330 as it will cause a data loop and prevent correct operation.
