Urgent: Older GPS may not function on or after April 6, 2019

On April 6, 2019 older GPS antennas and MFDs may cease to function.
I called Raymarine / Flir and they are testing the antenna I’m currently using (Raystar RS125) with my E120 Classic. They said it may still work, but they are not done testing. If it’s not compatible with the change and Raymarine does not release a firmware update for this discontinued product, I would need to purchase a new Raymaine antenna (RS130), Seatalk NG Starter Kit and Seatalk 2 to Seatalk NG Adapter for my existing E120.

You should contact the manufacturer of your GPS Multi-Function Display ASAP.

NjHere is the Info:

Upcoming Global Positioning System Week Number Rollover Event occurring on April 6, 2019.
If devices in use today are not designed or patched to handle this latest rollover, they will revert to an earlier year after that 1,024th week in April, causing attempts to calculate position to potentially fail.

  1. i had to replace a 125 a year ago. i saw what raymarine wanted me to do with wiring and decided to go with a nmea antennae. our rl70c display has a built in nmea port. wire matching was easy. antennae was $180 from defender.
