vehicle off track?

 

I know this had to be discussed at some point, however I can't find a simular problem on here, like I have..I updated my map on my 765t, did a hard reset, and my car, on the map, is off on the side of the track..(does that make sense?)instead of it being on the line, it's offset..weird, is there something else I could do, or should have done after my update?

Not sure since you tried hard reset.You may try a touchscreen recalibration.See http://goo.gl/pNRr5d

Almanac data

This is a guess on my part: It is possible that since a hard reset returns the nuvi to a "like new" state, that the Almanac Data has been lost. New units don't have Almanac Data either. It is easily remedied.

Almanac Data shows the GPS where the satellites are on a certain date. It allows a good fix more quickly because it is looking for satellites it knows are there.

Turn the nuvi on and leave it outside in an open area for about 20 minutes. It helps that it is not moving around while driving. It will download the Almanac Data from a single satellite in the southern sky. Being in Florida is an advantage because it is closer to you.

After doing this, drive around and see if it is fixed.

How about changing icon?

I have a 765t as well and the map update went fine with no problems. Maybe try changing the icon from it's present one to something else and see it unit reacts the same.
The other idea maybe to re-install the update.

Obviously a four wheel drive would go off the road!

dobs108 razz

I Agree With Dobs108

I think his suggestion of getting your Almanac refreshed after a hard reset will cure your problem.
As stated by him, leave it outdoors with a clear view of the sky. Whenever I see "ready to navigate" I know I have a lock on the satellites and should display my current location.

Let us know how you made out.

What's odd is...

What seems odd to me about this is that it's likely not a GPS accuracy issue since as far a I know, all Garmin On The Road devices have a non-disableable "snap to" feature that forces the vehicle icon to appear on the roadway:

http://www.gpsreview.net/snap-to-roads/

It probably is that Snap To may only apply when the offroad navigation is not selected and may not apply when in a mode other than automobile or truck.

I have seen this occur on my nuvis occasionally when in construction areas where the road alignment has changed and the nuvi can't determine what the closest roadway is thereby thinking it's offroad. If you're seeing this always, fkeddy, I'd check to confirm that you're not in offroad mode and that automobile mode is selected. I did check the 765T owners manual to see if disabling Snap To may have been offered on these units but saw nothing to suggest it is a User Setting.

Good luck and let us know what fixed it for you.

Maybe a bit more info might help

Did the problem exist before the last installed update? Does the problem happen everywhere or is it confined to a certain area? As far as I know the recent models by default place the vehicle icon on the closest road way. Earlier models had an option to do that and if not selected would sometimes show the car running in the ditch along the other side of the road.

not a good fix

I have seen the same thing as fkeddy describes in the Catskill Mountains of NY state. Snap to is not an issue if you do not have a good fix. Mountains get in the way of satellites. I saw the vehicle driving along mountainsides and not on the road.

In Florida, there are no mountains, but recently there have been solar storms to interfere with getting a good fix. Add that to lack of almanac data and it amounts to the same thing.

Just let the nuvi stay still until it gets a good fix.

dobs108 smile

Usage mode / navigation mode?

You didn't by any chance change the usage mode to something other than automobile or change the navigation mode to Off Road did you? I think some combinations of those modes can turn off the "snap to road" function that is used for automobile navigation.

Snap to road

Maybe, but it happened to me once on my 755T ... it showed me a couple of hundred yards south of my position, in the cornfield traveling parallel to the road I was driving on (we don't have mountains in Iowa smile ). I had been tinkering with my nuvi for Geocaching and changed the modes ... forgot to change them back. As soon as I corrected the modes, I was back on the road again. It could have been a coincidence that I got a better fix at the same time I corrected the modes, but it seemed like changing the modes to on road automobile navigation is what fixed it.

This was 5 or 6 years ago, and I do think the maps were much less accurate back then than they are now, making snap to road much more critical even when you had a good fix.

it's been a few weeks since I did the update, then shut it down because my charger broke, it wasn't happening before, just today when I turned it back on, and it showed the truck running along the side of the road

I don't think I have it set to off road, but maybe it's something as simple as that, it's never happened before, maybe I hit a few buttons too many.. surprised

I agree that it's unlikely. If you've done a Whereto route with offroad selected, you'd instantly know much more was happening since you'd be given a As-The-Raven-Flies route.

Southern sky

After checking, I am wrong about the southern sky. That is for the WAAS satellites, and most nuvis don't use it. The 765 can download the Almanac from any satellite it can see, after putting it outside for 20 minutes.

As member fkeddy stated in her first post that after the map update she did a hard reset, that would put her settings back to default. Automobile is the default setting.

Any possibility the wrong

Any possibility the wrong map datum has been selected? I believe the effect of using the wrong datum is an offset error. Doesn’t seem likely because some devices don’t allow selecting the datum and even if they do it will be off in some obscure menu – not easy to accidently change. (I cannot select the datum on my Nuvi 50 but can on my GPSmap 60Cx.)

It also may be a registration error on that portion of the map as well.

Simulate a route

Try a few simulation routes on your unit.See http://goo.gl/awoHFe for instructions.

Note Simulating a route allows you to see how the device will navigate without you actually driving the route (the vehicle icon will move and the device will speak the turn instructions). This feature is useful when you are in a location where a satellite signal cannot be accessed or for calculating a planned route.

Doing a simulation route, if things work properly can rule out the possibility of a corrupted map causing the issue.

I took a long drive up out of the valley here, put in to navigate to a certain place, and it did the same thing, as a matter of fact, it was off on the distance to turn as well, and my POI's are not working either...hmm.. confused

Would it make a difference with simulation? I took a long drive up the highway, and it did the same thing

That could be the problem! laugh out loud

Reinstall map?

The only thing I can think to try at this point is to reinstall the map. If you have a 4 GB or larger SD card, you could install to SD, then temporarily disable the map in internal memory and test the reinstalled map on SD.

Incidentally, how much free space do you have in internal memory of your nuvi. I have never heard of this type of problem being caused by too little free space, but it is something else to check.

Just after 2015.40

I had similar experiences in the past showing my car north (always) of my real position. It also happened in specific areas. Just after the 2015.40 update, I had it again, but somewhere else. Like in the last, a few restarts got rid of the problem. I think the library loading is at fault.

Check the number, strength and accuracy of sats

fkeddy wrote:

Try holding your finger on the sat signal strength icon in the upper left corner until the sat info screen comes on. That will show what sats you are receiving, how many and the accuracy in feet.

http://img.gpsreview.net/wp-content/uploads/garmin-satellite...

I normally see at least 5 sats and an accuracy in the 10-20' range after it has had a chance to lock in for a period of time.

If the accuracy is in the 100's of feet range you would be seeing the problems with offset location from the road on the map.

Be sure to check the amount of free space on your 765T before you attempt to reinstall the map. After removing unneeded files on my 755T, I was able to fit the full NA map on it, but it is very tight on space. I think the 765T has a little less free space than the 755T because of the bluetooth support. If you are short on free space, you may need a SD card to get a successful map install.

thought I'd pass on what had happened, it was the Garmin Express, the version I had when I downloaded the update was old, I installed the updated version of Garmin Express, plugged in the 765, it updated my software and map, and everything is working like a charm, and the map icon box is no longer grey...thank you everyone for the tremendous amount of time and help you've given me, ya'll are amazing.. wink
