Internal GPS showing wrong date

2012 Simrad NSS12 (pre-evo models).

No issues until last week when we went out and I noticed no time displayed on screen in any page/display (wte of Satellite view). Also noted GPS receiver icon was RED.

Track data had correct lat/long, but all track points showed 12/31/1969 19:00:01 for date/time. Ran again this week, same symptoms. On Satellites page seeing correct position, and time, but date shows as 27/03/2099.

Any thoughts on correcting would be greatly appreciated. Did a Google search, but not much on these older devices.

purely a guess...


An internal battery finally died.


I had a PC behave the same way long ago, far away. new BIOS battery fixed it...


They want us to throw stuff away by the time this happens now...

I don't know if this is your problem, but there was a very similar problem with avionics made with a certain popular GPS chip set. A register overflows, and the date goes bad. Everything else works fine. Is the GPS internal to the plotter? GPS receivers are very cheap now, I'd just add an external one.

I was thinking the exact same thing.

Yes, internal. Going external is certainly the solution if I can't get it figured out.

This has hit Simrad across the board with a number of model products. It’s a bug and you will have to wait for a fix. More info is available on the hull truth.

I have the same model with an external GPS sensor. I have also just lost the time from the corner of the screen in the last few weeks. I suspected that it may have been when I changed the time to allow for our local day light saving especially as being GMT + 13 hours. But after reading this I’m now thinking a bug or program glitch. Also a word of warning. I have a low bridge to negotiate to get back to my mariner, to check the tide height I use the tide chart on the Simrad unit. It now doesn’t change to the current date automatically so could of easily caught me out had it not been so obviously far out (bad seamanship I know). The same could maybe happening with your unit.

It seems the consensus is batch of bad GPS chips thatand manufactures are working on a fix.

Also a good thread on the Cruisers & Sailing forum
Anyone else having trouble with time/date display on Simrad MFDs? - Cruisers & Sailing Forums

E-mailed SIMRAD and received this response ... same as all the other manufactures I'd guess.

"This is still in process with no set ETA. We're working with the GPS chipset manufacturer to try and integrate a fix into our systems."
