Troubleshooting Your GPS Connection
• Your Plotter/GPS receiver must be capable of sending the proper sentences
(listed below) set for NMEA 0183 (Check your Plotter/GPS instructions for
information.)
• Verify that the plotter/GPS device is sending GPGGA, GPGLL, GPRMC, GPVTG, or
GPGNS sentences. (Check Plotter/GPS Instructions.)
• If you are still not receiving latitude and longitude, you can try setting the plotter
to send just a single GPGGA sentence.
• Have a technician check the plotter/GPS using test equipment to verify it is
sending the GPS sentence.
• Check the solder points on the radio and plotter connectors. Some connectors are
very small, increasing the likelihood of solder bridging.
