I am running an informal poll to see how prevalent Zero Off antenna failures are.
This week I found out the hard way that unlesss you regularly check your diagnostics screen you may have one antenna that has failed. In and of itself not a big deal, until the other one fails. I suggest everone make a habit of periodically checking your diagnostics. Our neighbors have been kind enough to let us use their boat in the meantime, ('13 TXI) and on a whim I looked at their diagnostic screen and sure enough gps1_fail. So out of four antennas on two boats less than two years old, three antennas have failed.
The worst part is that the manufacturer has still not been able to replace them despite being contacted three days ago. Today I found out thry have parts in stock now, but are not interested paying for Saturday delivery.
