Lane assist (lost after update to NA 2013.20)

Since the lane assist data is part of the map data, and not a separate file like Junction Views, the only 2 suggestions I can think of is to download the map update again or before you do that, perform a hard reset on your Nuvi to see if that helps.

Remember that doing a hard reset will delete all your favorites so be sure to back up the current.gpx file before you reset the unit.

I once saw that with the previous 2013.10 map and got really worried. I think I may have been tinkering with moving my large jcv file from the nuvi to a SD card. I found on my 855 that a battery removal/replacement fixed it so I'd go with the already-suggested hard reset and I bet they'll re-appear. It's definitely worth a try since it's so much easier than a full re-download/reinstall.

You don't mention what nuvi you use. If you haven't fully powered down (not simply put the nuvi "to sleep") and have the ability to do so, I'd try a full power-down/reboot first.

I agree it seemed very odd to have Lane Assist simply disappear while the rest of the nuvi functions including Junction View were working perfectly normally.

Plz report back with your results.

I did a hard reset as suggested (Nuvi 3490LMT), it did not work. I re-installed the3 map and that also did not work.

Any other ideas?

I would restore the previous map version for testing just to confirm that the Lane Assist problem is tied to the 2013.20 map. Then, it is probably time to call Garmin.

I had that problem since updating to 2013.10 but I assumed that it would be corrected with 2013.20. I called Garmin, they want me to call them so they can remote into my PC to try to fix the issue. I have mor then one PC and I tried two now with the same result.

So Garmin was unable to fix the problem? Or are you saying they were not able to establish communication with your 3490 through either of your PC's? Is your unit still under warranty? If so, I would call them again and if they can't fix it, it is time to ask them for a replacement unit under warranty.

I usually have 2 backups of each GPS. One when I first got it and a 2nd that I backup every so often when I know things are working good. Do you have a backup from when it was working? Try using that backup.

Just to be clear ...
You do know that lane assist only shows when you are navigating a route (have a specific destination entered)? Lane assist does not show when you are just navigating in map display mode without an explicit destination. All nuvi's with lane assist work this way.

Yes I do, I owned GPSs since the 1980 and currently own nine, I am very familiar with how they work. Garmin did not have a chance to hook up with my PC, I placed the call and after 50 minutes of waiting my phone battery went dead and it was too late to call again. I will give Garmin another chance to fix the issue.

Thank you to all for helping me resolve this issue and the advice

Sorry, I didn't mean to imply that you didn't know your GPS technology. We have had posts from forum users that didn't understand the relationship between lane assist and navigating to a destination, so I was just making sure.

Wow, that must have been an interesting GPS device you had in 1980.

I just purchased this GPS, but I am seeing the same problem I think, although I am not 100% certain as I updated right when I got it before using it.

NO PROBLEM AT ALL, YES I HAD TO WEAR A HARNESS TO USE IT, WITH AN ACCURACY OF 100 YARD IN ANY DIRECTION AND SA TURNED OFF. IN FOG OR SNOW THERE WAS NO CHANCE OF FINDING YOUR LOCATION, IT MUST HAVE WEIGHED ABOUT 35 LBS.

WTF?

the size of a small suitcase. A friend was one of the engineers working on the project and brought it to the service station where all us car guys used to hang.

I find that the 2013.2 is better now than the 2013.1

Before it wanted to shuffle me off into the, what we call collector lanes of the highway even on a 20 some odd mile trip. Now when I enter a route it will take me into the center core with far fewer exits. The Lane assist is working well also. I did try the larger JCV file and have reverted back to the Garmin installed 459 MB file.

I have a 3490LMT and haven't updated it in months (like since April) so is 2013.20 a problem with the 3490LMT and lane assist? Should I wait to update the unit?

I was not being funny, this is absolutely true, the GPS I was using back in the 1980s belong to a mine in the North West Territories and was carried around supported by a harness due to its heavy weight (I must admit however that it might have weighed less than 35 lbs.). When selective availability was in effect, the accuracy was at least 100 meters in any direction. I really meant no problem and understood why you would want to make sure that I understood about lane assists, many users are new or have very little experience with GPS and need people like you to help in solving problem.

I would do a hard reset and get the file again. I know you are speaking of lane assist, but my last update got me so many junction views, it is almost irritating.

I tried that and it did not solve the problem, thanks for the suggestion.

What was her name????

Can you give us an update, were you ever able to have Garmin connect to your PC to diagnose?

You say the problem began with Ver 2012.10 and 2012.20 did not cure it. This leads me to believe it's not a map issue and a hard reset didn't cure it.

Have you tried to reinstall the latest firmware for it?

I would copy the GUPDATE.gcd from the Nuvi to your PC, then delete it from the Nuvi.
Then I would use WebUpdater to install the latest firmware. Before doing so please MAKE SURE the nuvi's battery is fully charged.

So, let me get this straight, you're no longer receiving lane assist in your local area? Have you traveled much outside your local area? Garmin will sometimes remove lane assist in certain areas and then re-add it in a later update. The same thing happened to me in my local area with 2013.10. Intersections that I knew for a fact had lane assist no longer worked. It was because Garmin had removed the data from that intersection, but then for some reason, it was added back in for 2013.20. Why Garmin does this, I am not exactly sure, but my theory is that Garmin does that when Navteq has recently driven the area and is in the process of making a lot of changes to the road attributes. But to make sure your GPS is working correctly, try simulating a route in a large metropolitan area, like Orlando or Altanta, with a lot of exits and turns on major roads and interstates. If you get the lane assist arrows on this route, then that means your device is working properly and the reason you don't see the lane assist arrows is because Garmin temporarily removed them for whatever reason.

updated but got it back the next update. Try going out of your area to see. Personally, I think the programmer missed the input on the new map.

For the recent folks asking RogerLL for input, I add my findings.

With the previous 2013.10 map, I also one day found that I had lost Lane Assist arrows although the GPS worked normally otherwise, including showing Junction Views.

I believe this occurred shortly after I had tinkered some with jcv files (using the non-default large JCV file on my nuvi 855, trying it internal to the nuvi and on a SD card) although I'm not 100% sure of the timing.

This was very surprising to me and pretty scary. For me, I removed and replaced the battery from my 855 to reboot the whole device. Since then (knock on wood), I continue to see Lane Assist, both in the past with 2013.10 and now with 2013.20 maps.

To me, this indicates a temporary glitch in my nuvi's system that was cured with a reboot and not a map file error in the previous 2013.10 or current 2013.20 map. I realize that RogerLL's issue is somewhat different than mine in that a reboot and even hard reset hasn't cured his problem. I just want folks to know that I've seen the issue once with one map version and was able to fix it. This may affect the sleuthing that's going on to see what's happening.

The frightening part of this for me when LA was lost was that like so many of us, it made absolutely no sense to me to have a fully functional nuvi with the exception that the useful LA feature of the device was totally missing.

RogerLL, you reported this same problem a year ago (http://www.poi-factory.com/node/34050) with the 2012 map updates on a 3790LMT, and now with the 2013 maps on a 3490LMT. Were you ever able to resolve the problem on the 3790, and if so what was the solution? I suspect there must be some common cause of this on two different nuvi's with different map updates ... maybe some unusual combination of settings you use that other users seldom experience? Can you give us any additional information? Maybe you could give us a sample route where you expect lane assists that we could test on our nuvi's and see if we can reproduce your issue.

1.Can you give us an update, were you ever able to have Garmin connect to your PC to diagnose?

I decided not to persue the idea of having Garmin remote into my PC for a try at fixing the issue due to time restraint.

2.You say the problem began with Ver 2012.10 and 2012.20 did not cure it. This leads me to believe it's not a map issue and a hard reset didn't cure it. Have you tried to reinstall the latest firmware for it?

I said the problem began with the installation of the 2013-10 map, I have tried many different scenarios, backed up the GPS then deleted all files relating to the map in the system directory and reinstalled the 2013.20 map and it did not fix the problem.

rame1012: So, let me get this straight, you're no longer receiving lane assist in your local area? Have you traveled much outside your local area? Garmin will sometimes remove lane assist in certain areas and then re-add it in a later update.

1. I am starting to believe that this is what is happening, I was simulating travel in a different area and a saw a lane assist.

alandb: RogerLL, you reported this same problem a year ago (http://www.poi-factory.com/node/34050) with the 2012 map updates on a 3790LMT, and now with the 2013 maps on a 3490LMT. Were you ever able to resolve the problem on the 3790, and if so what was the solution?

1. No the problem was not resolve at that time and I decided to replace the GPS with the 3490LMT and there was no issue with the new GPS.

Thank you all for helping me resolve this issue.

So the problem is not related to one specific unit but the update itself it seems. Been holding off....

Thx.

I don't think we can conclude that Preroll. I haven't heard anyone besides RogerLL reporting a problem with Lane Assists after the 2013.20 update. I am still hoping RogerLL will give us a sample route that demonstrates the problem. With that we should be able to verify whether or not it is a problem with the map or with his specific nuvi.

OK thanks. I'll continue to hold off on updating my 3490LMT then.

I was going to update my Garmin prior to a couple of trips that are coming up....but think I will wait now.

all three of my gps and has not seen any problem with Lane Assit or JV.

I can't -prove- it, but I -think- the issue or confusion surrounding Lane Assist since the new map update might be because it's acting a little different now, verses the previous map version.

I believe that under map v2013.10, the small Lane Assist box on the upper left of the screen would show the lane assist as soon as you got on the highway. In others words, the exit could be 150 miles away, but the little multiple arrows would appear in there showing which lane you should be in when you were approaching the exit.

After v2013.20, the box just shows the single (curved) arrow for the next exit until you get close to it. This is how my 2595 is operating now. When I get close to the exit (haven't measured -how- close) the box changes to the lane-assist mode and shows you what lane you need to be in.

Again, I can't swear to this because I can't go back to map v2013.10 to prove it. Someone still running that version will have to confirm.

If I'm proven wrong I'll gladly retract! Just trying to help folks resolve this mystery....

Good luck!

I have been travelling the same route for many years to work back and forth. On that route, before updating to 2013.10 and 2013.20 there were multiple instances of lane assists but since the update all of them have dis=appeared, not a single one remains. However while simulating another route, one single lane assist came up, I now believe rame1012 when he suggested that Garmin must have disabled the lane assists for my area but I really wonder why they would have done that in the first thing.

I took a trip from park city Utah to Layton Utah, one week and there were lane assists, did a map update and did the same trip the following week and the lane assist were gone. this was a previous release.

So why not do as Alan suggests, give us a start and end location (doesn't have to be an exact address, just the streets and city involved) and let us check the route on our Nuvi's.

Really glad to see this thread. It reminds of why I came to POI Factory to begin with and that was people trying to help each other. I've been disillusioned from all the whinning regarding smartphones. I updated my 755w this weekend and ran into some files downloaded from this site and really appreciated it. This thread remained me of all the good on this site. Sorry to digress from the main topic but wanted to thank all of you.

Now sinice I downloaded 2013.20 let's see if I have lane assist. I rely on it heavily in places I'm familiar with since I don't hear well.

How do I post the test route

No need to post the route, just give us a start and end location. For example:

Start - Maple Street, Seattle Washington.

End - John Ave, Federal Way Washington.

We can plug this into our Nuvi's while in simulation mode and follow the route to determine whether lane assist arrows appear or not. If you want to supply exact address (329 Maple Street, for example) this would allow us to give you exact feedback on what you should be seeing.

Start - Nisku AB
End - 2287 Terwillegar Dr NW, Edmonton AB

Thank you

My 2450 has always shown the single arrow in the upper left corner until I was close to my turn. This is how my 2450 came when new. When I come close to my exit the single arrow will turn to arrows showing all lanes with the ones not to use grayed out and the ones to use are white.
I did my update and my unit still works great. The lane assist is the same as when I bought it new.

Still have my junction view also. I have never changed my junction view from whatever downloads with my map update.

I don't see any problems with the update on my 2450 unit.

Re: >>I don't see any problems with the update on my 2450 unit.<<

Well, maybe it depends on the highway, location, or the position of the planets then. ;^). But I'm 99.9% sure that under previous versions of the map, the lane assist would give you the correct lane indication many miles (and hours in some cases) before the exit. It struck me as being very silly, especially if I was in eastern MA and the exit was in Western NY somewhere. (I90)

Lane Assist arrows, from start:

1. Turn right on 10th Avenue (right arrow, 90 degree bend)
2. Take ramp to AB2 towards Edmonton (right ramp arrow)
3. Exit left to AB216 (left ramp arrow)
4. Keep left to AB216 West, towards Anthony Henday Drive (left "Y" arrow, right grayed out)
5. Exit right on Terwillegar Drive (right ramp arrow)
6. Keep right onto Terwillegar Drive North (right "Y" arrow, left grayed out)
7. Arrive at destination, on right (Destination mark)

Ramps and exits could benefit from having the portion of the road not to be taken grayed out, however they aren't.

Perhaps Roger would be willing to simulate the same route and use the screenshot feature of the GPS to show us what he's seeing?

I see exactly what Strephon has posted above.

My definition of "Lane Assist" is that it shows multiple lanes with the lanes you should use being colored white and the lanes not to be used, grey.

What I'm seeing in the route you provided are NO lane assists, as per my definition, but simply the normal turn indication arrows that you would see whether lane assist was available on your Nuvi or not. Whether you had lane assist arrows on that route prior to Map Update 2013.20 or not, I can't say, but you don't have them now.

When I used my 750 I had the large lane assist, no junction view. The lane assist took up half the screen showing all the lanes with the ones to take highlighted.

With my 2450 it has the lane assist in the top left corner and when the junction view comes on it showes all the lanes with the ones to take highlighted.

Don't know if I am calling them the right thing but this is what mine does.

Better than I can say are photos.
This is what Garmin has on youtube for lane assist and junction view. The only difference in mine is that my junction view is only half screen on my Nuve 2450.

There is less lane assist data in 2013.20 for RogerLL's Alberta route as well as for a random intersection I picked here in Ontario.

See the following screenshot montage that shows LA data lost between 2013.10 and 2013.20:

http://goo.gl/KTRn8

They (Garmin) have either reduced, eliminated or screwed up lane assist availability, or all, some or combination of all three. The proof is in the pudding.

Perfect, that looks to be exactly what RogerLL is saying about Lane Assist appearing less in the new update for the Terwillegar Dr portion of his test route.

then the lane assist will be added back/corrected in a future update. But why Garmin removes this information in the first place is a mystery to me. With each map update, lane assist coverage should only expand, not the opposite.

Thanks RogerLL for giving us a route that demonstrates the removal of lane assist coverage. I was able to reproduce the issue on my 755T with the 2013.20 maps ... got no lane assist coverage with your sample route. I reinstalled an old map (2012.40) and got 4 lane assists on the same route.

It is a mystery to me why Garmin would reduce lane assist coverage on a map update. So far I have not found any reduction in coverage in my local area, but it does make me wonder just how much they removed and makes me uneasy about this version of the map. I do hope they restore the coverage in a future update.
