Hi,
I am new to this site so please bear with me. I bought a Matrix 55 combo unit in 2005. A Cancer diagnosis shortly after restricted me from using my boat until now that I have finally got myself back to a level of fitness to try and venture out again. I was installing a GME VHF radio and tried to connect it to the NMEA output of the Matrix without success. The next thing was I lost the GPS function altogether on the Matrix. I have checked all of the connections, plugs and wiring and all is OK. The only thing I can put it down to is the receiver/antenna decided to malfunction just at the time I was playing around with the wiring. I don't think I connected any wires around the wrong way, but who knows.
Are these antennas prone to break down as there seems to be plenty for sale on the internet?
Does the unit only recognise the navigation and the main menu only show the navigation icon if in fact the antenna is connected.
I have ordered a new antenna but in the meantime if any one can throw any light on what may have happened it would be appreciated
On the subject of connecting the GME radio, there are a black and red wire from the GPS plug on the radio and the pigtail on the matrix has a black,red and white wire. I originally connected the black wires together and the white wire on the matrix to the red wire on the radio. I also turned on the NMEA output in the advanced menu on the matrix.
The latitude and longtitude did not appear on the Radio.
It was shortly after I disconnected all the wires, not being successful that the navigation/Gps went down on the Matrix.
I hope the new Antenna gets me going again!
Anyway look forward to any suggestions or advice.
Thanks John
