GPS Speed limit corrections - central database ?

 

I travel up/down east coast (i-95,i-77,i-81,i-75) and see a lot of errors between POSTED limits and GPS info. Is there a central system for that , or would each mfr need to correct ?
I submitted a few to Garmin and HERE, but no way I can detail ALL the errors that i see.
Would be nice if GPS mfr made it easy for us to save/upload coordinates and CORRECT info. So driving along , click Menu- report - wrong speed posted - and enter correct mph info. Next time we connect it gets uploaded, they confirm and changed on their next map.

But would make sense that that is CENTRAL db and not, say, Garmin specific

Speed limit

I seem to remember that if the speed limit is wrong on the GPS that there is a way to adjust YOUR speed limit display.
If it works for all I do not know, but it is something like to hold the speed limit sign and then it switches to a setting where you can enter the correct limit. But it should only be useful if you drive the same roads every day I suppose.

Maybe this is useful for you:

The nuvi 2460 is one of them. The feature was very short lived so maybe it was only available on the 24x0 series or at least the series that were introduced at about the same time around 2011:

A chore

I found it to be quite a chore on my 2460. I had a few hundred mile stretch along a TX state highway that I traveled several times which was incorrectly posted. I found that my revised speed limit was only good for a few miles so I had to correct the limit several times an hour until I finally left the highway.

I agree

I agree that that would be:
1.) Too distracting to do constantly while driving solo.
2.) Speed limit signs along the road are sufficient.
3.) You should NOT rely on electronics for EVERYTHING !

Worked on these...

I was able to reprogram the speed limits on the Montana and I reprogram the speed limits on the Garmin North America iOS app.

One thing I noticed with my 2460 was if you're on a highway that changes speed limit often and you try to correct it at each change the next time you're on that stretch of road the last speed limit entered was the one that showed for the entire stretch.

I've noticed MANY MANY errors over the years on several different interstates & don't rely at all on the speed limit that my unit displays even though I have the latest mapset.

Doh! Not the 2600 series. Oh well, out of sight, out of mind.
