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 GPRMC, GPGGA, GPVTG, GPGLL, or

GPGNS sentences. (Check Plotter/GPS Instructions.)

•

If you are still not receiving latitude and longitude, you can try setting the plotter

to send one sentence at a time (if possible). This can help it find the most

compatible 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.
