egavasm,

Q1. The gps is Raymarine GPS Compass E32042,there are two wires from it that are connected to another cable that runs directly into the MFD.
A1. It is recommended that you verify that the system has been interfaced to no more than one source of GPS data. If not, then please note that there are three methods of interfacing a RS125 GPS Sensor to an E-Series Classic MFD, and all would involve using all five of the RS125's leads:

- NMEA 0183:



- SeaTalk:



- SeaTalkng / NMEA 2000: The MFD must be updated with E-Series Classic MFD v5.69 software. The MFD's SeaTalk 2 (SeaTalkng/NMEA 2000) port will be connected to a spur socket of a powered and properly terminated SeaTalkng / NMEA 2000 backbone which includes a SeaTalk to SeaTalkng Converter which has been updated with v2.03 SeaTalk to SeaTalkng Converter software. An A06061 / 4.92in (1.5m) E-Series to SeaTalkng Adaptor Cable will be used to accomplish this end. The SeaTalk to SeaTalkng Cable supplied with the E70196 SeaTalk to SeaTalkng Converter Kit will be connected to the SeaTalk (yellow) socket of the SeaTalk to SeaTalkng Converter and to a D244 SeaTalk Junction Block. A SeaTalk Cable will additionally be connected to the D244 SeaTalk Junction Block. The other end of this SeaTalk Cable spliced to Raystar 125 GPS cable as follows:
----- red and green leads of RS125 to red lead of SeaTalk Cable
----- yellow leads of RS125 to yellow lead of SeaTalk Cable
----- brown and bare/black leads of RS125 to shield lead of SeaTalk Cable

Should you have verified proper interfacing of the Raystar 125 GPS Sensor to the MFD, then it would be recommended that the GPS be commanded to be restarted. Should the problem persist thereafter, then you may want to consider recording your MFD's settings, backing up you MFD's waypoint, route, and track data, and then commanding a System Settings & Data Reset. Should the latter fail to correct the issue, then the problem would appear to be rooted within the GPS sensor itself. Before replacing the GPS sensor, it would be recommended that its internal CR2032 memory battery be replaced and that the system be tested again when underway. Should the problem persist thereafter, then it would be recommended that the GPS sensor be replaced with a Raystar 150 GPS Sensor.
