In the March 2019 edition of PC Magazine there is an article about the possibility of some GPS systems failing come April 6. Evidently something to do with resetting the timing stamp every 20 years. Anyone heard of this? According to the article any GPS systems built after 2010 should be fine or those that conform to the ICD-200 or GPS-200 specifications.
GPS units < 10 years old are not likely to be affected by the 4/6/19 timing clock rollover.
Sounds similar to the doomsday prediction of Y2K.
Thank goodness It wasn't nearly as much of a problem as predicted.
I hope this isn't a big problem either.
Response From Garmin
I received the following response from Garmin concerning the 2019 rollover:
No, it does not look like there will be any problem with the Garmin devices with the 1024 week rollover in 2019.

Not unit specific by any means but still encouraging.
And a relief too.
Lets hope they're right!
Let's declare the 6th a no driving day.
Everyone else will run off the road blindly following the GPS while we can sit at home sipping our favorite drink and smiling.
When the 7th rolls around I guess we walk to church, or wherever.
I'm safe after that because I still have some old paper maps and a US Atlas somewhere.
I've filled the pantry just in case I can't find my way to the grocer.
It may keep the older planes from beaning you on their way down!
Guess we will just have to stay off the roads that day.
Ongoing discussion about this here:
This would be a good excuse to tell my boss when I'm late!
two more days and we'll know one way or another now !
Me, I'm not holding my breath for anything untoward to happen !
I know that some older Garmin handheld devices in the Etrex line exhibited this failure several weeks ago because of the way Garmin implemented the date calculation algorithm. Garmin has already issued software updates for those devices. This tells me that Garmin has actively tested most of their devices that are still in general use, so I don't expect too many surprises.
And everything is working the way it is supposed to. I even ran a simulation and it appears that the April 6th bug will not affect the 350. I didn’t think that it would, but I just wanted to check and make sure.
Is the date and time accurate? If Nuvi 350 isn't affected, my 760 which is newer than 350 should not be affected either. I have not switched on my Nuvi yet. It's still April 5, 9:28 pm where I live.
I just booted my Nuvi 1490,3597 & RV760 GPSr's and all appear to function normally.
...is accurate. I can’t find a way to pull the date up on the 350, but since the time is correct, I’m taking it for granted that the date is correct also.
mine is still working well TODAY
My 3597 still going.
Both, my 855 and SmartDrive 50 are working as they should!
Finally got around to loading 2010.10 on my 660 SD Card...
and updating POI's.....
It boots and shows map.... OOPS! Wrong time...
So took to car and let it boot and get satellites... Now it's fine... !!
I have two DriveSmart 61's, both up to date in every way, one was perfectly fine on April 6, the other, somehow "automatic" was unchecked and the time was off by two hours.
I set my destination for the gym and ended up at the donut shop!
I set my destination for the grocery store and ended up at the diet center!
I set my destination for the doctor's office and ended up at the auto shop!
I set my destination for the school and ended up at the library!
I set my destination for the office and ended up at the bar!
I set my destination for the park and ended up at the dump!
I set my destination for NYC and ended up in LA!
mine is fine
April 6 came and went. Still here. Whew.
I have an old Garmin Etrex purchased about 2005 that's been sitting in a closet for many months. Software rev is 2.14(2002). I got it out on Sunday 4/7/2019; powered it up; found satellites and it then displayed the correct time/date in my time zone. Is there anything else that could have been affected? What else to check for? My Garmin Nuvi for the car is up to date.
Both my 3790, and 775T had zero problems.
Thanks. My Nuvi 760 works fine too. I don't know what is supposed to go nuts on Apr 6. It takes me to where I want to go so it's good. Time stamp is accurate. In fact, it locks on GPS satellites a lot quicker than it did before.
Was supposedly affected according to the serial number check...downloaded the patch and after a little wrangling because TT said it was too old to update it works fine.
This is helpful info.
No problems on any of mine
I guess consultants are pleased though ....... nothing happened? ..... Thanks to them...
I doubt there will be any problems
All mine are running OK, had to check the date of the post , thought it was April 1st.
I have an old GPS60 handheld. That's more than 10+ years now. Guess I should check it or chuck it at this point. Lol!
I just powered on my 3 eTrex GPSs (2 blue Legends, 1 yellow eTrex) and all 3 found my location and have the correct date & time. These are the rs-232 variety and are vintage, but work well on my boat's rs232 comms.
At least for Garmin. I pulled out my Garmin GPS 48. mfg in 1996, f/w ver 4.60 2003. I think you can call it OLD.
It has been a VERY LONG TIME since it saw batteries. Having a little trouble with the LCD screen contacts, but it eventually fixed most of the missing lines so I can read it. After a while, it finally found enough sats to give me my correct location and the correct date and time. No auto DST so I had to change the GMT offset from -5 to -4.
But all seems good.
So don't worry about ANY Garmin.
Wow. eTrex likely makes you the winner for oldest GPS. I'm guessing you were likely a geocacher. My "newest" GPS units are nuvi 760s. I don't anticipate any issues with them but I do still need to update the maps. I think I've missed the last two updates. We'll be taking a 5 or 6 week camping trip in a couple of months and I'd like to have updated maps for the trip.
Well, I guess my 660 is OK. Shows correct time and location when turned on today.
Can't find the list of 660 firmware updates at Garmin anymore, but I guess the last one (4.90, 18 Mar 2010), or earlier, had the fix.
Seems like Much ado about nothing.
See this: http://www.poi-factory.com/node/46396
Good here too
Thanks alandb. I knew I had the latest revision, but I just wanted to see if Garmin listed an update for the newer satellites. I didn't find any mention in any of the revs, so I guess it was there when the model was launched since my 660 seems to be working just fine.
Not the first or last rollover.
Had a guy, every day telling me how he was stocking up on food and stuff for Y2K EOW. One day he asked me what I was Stocking up on, My answer "Don't need anything, you've got everything I need already"
Both my 2495LMT and 1390T is working just fine.
Does anyone know how to check what firmware version our device is currently using?
Best to check the owner's manual (User Guide). It varies some for different models.
If you don't have one, you can download it at Garmin.com support.
If you don't have one, you can download it at Garmin.com support.
Thanks. I did that last night. Can't find it in the Nuvi 7x0 user guide. I've also tapped everything I can tap on the device but can't get firmware info.
