Lane Assist odd errors
    15 years
|
Here in Albuquerque, Lane Assist appeared very little save on the Interstate intersections until the three most recent map updates. Now they are very common, even including the 25 mph exit road from my residential community on to a four lane road. Sadly, that specific intersection displays wrong lane assist advice on my Garmin 855 nearly every time I drive through it while in active navigation. It shows the wrong number of lanes, with the wrong turn options available on the lanes, and the wrong one of the lanes advised for my actual routing. All this time, the voice prompt and the arrows on the actual map show correct advice. I've seen similar Lane Assist errors for at least two other intersections in Albuquerque, though most locations work fine.
When the error still was present in the most recent map release, I started preparing a mapreporter item for Navteq, thinking this most likely is a map database problem. But in preparing that report, I noticed that the error depends on the NEXT advised turn after the erroneous one. It shows bad information if my route calls for a prompt left turn at the closely spaced next intersection (which also has LA data) after the first right turn. In fact, the bad LA matches that next turn, save that it displays too soon and that it counts down the distance to the first turn.
In contrast, when my route calls for me to continue without turning through that second intersection, and a mile later to turn right at an intersection that lacks LA, the first turn LA is displayed correctly. So perhaps this is an 855 firmware bug, or a Navteq database error, or an incompatibility between the two.
I've posted a screen shot of the bad turn advice at this intersection (San Bernardino NE & Tramway Blvd NE in Albuquerque NM) on my photobucket site at:

I've posted a screen shot of the good turn advice at this same intersection at:

Is this a known problem? If not, I'd like to post waypoints so that volunteers here with other Garmin models than my 855 can try simulating the same turn to see if the error varies with model (and therefore firmware).
Not consistent
My LA odd error in this thread was not fixed yet. Did anyone else get their error fixed??
Since I picked up the Nuvi 1450LMT, I updated the FW, registered it and updated the maps to 2012.40. The odd lane assist errors still exist on both 765Ts and the Zumo 665 but all of the known LA errors are correct so far on the 1450. So does that make the lane assist errors a FW problem on certain units?

late
Only LA error I have noticed on my 765t is that the snapshot of the turn sometimes comes up too late.
Unless you are the lead sled dog, the view never changes. I is retard... every day is Saturday! I still use the Garmin 3590 LMT even tho I upgraded to the Garmin 61 LMT. Bigger screen is not always better in my opinion.

I also have 1490T and no LA errors
I have not noticed any similar errors on my 1490T. We have many complicated/adjacent exit intersections here in Tampa and it seems to get them right.
Hope they can get a fix for your model(s).
Simulation Voluteers Wanted
This odd Lane Assist problem now appears to be a FW issue on different models. If you have the latest maps and FW updates on you Garmin maybe you can load these POIs in a Custom POI file or in your Favorites, run 2 simulations from Start to the End Turning Left/Right POIs and post your results.
If your LA is correct at 2 miles from the turn you will see a 3 arrow LA with the left 2 pointing straight and a 3rd arrow on the right, bold and showing a right turn.
If your LA is incorrect at 2 miles from the turn you will only see 2 straight arrows with the left arrow bolded when navigating to End Turning Left or the right arrow bolded when navigating to the End Turning Right. The LA at 2 miles appears to be displaying the 2nd LA which is the split at the top of the exit ramp for both LAs at this exit.
Note that in either case at 1 mile from the turn the JCV pic should be correct and the LA and JCV for the ssssssplit on the exit ramp should be correct.

I plan on sending the test POIs and results to Garmin. That is why you need to have the latest FW and map updates since that is probably the 1st response they'll send back.
There have been numerous locations that produce the same LA problems as this one. If you have a location that has this problem you can also post simulation start and end POIs like I did above to send along with the results to Garmin or for others to also test. I'll start naming the POIs with a prefix AA_, AB_, AC_, etc., for sorting purposes and put them all in a single file to Garmin.
Thanks

Thank you for helping us out with this problem by sending your results into Garmin. The more complaints they get about this issue, the more likely it is to be fixed.

On my 765T
If your LA is incorrect at 2 miles from the turn you will only see 2 straight arrows with the left arrow bolded when navigating to End Turning Left or the right arrow bolded when navigating to the End Turning Right. The LA at 2 miles appears to be displaying the 2nd LA which is the split at the top of the exit ramp for both LAs at this exit.
Note that in either case at 1 mile from the turn the JCV pic should be correct and the LA and JCV for the ssssssplit on the exit ramp should be correct.
On my 765T, I saw only the 2 lane arrows. If I was headed to the left of the freeway after the exit, the left of the two arrows was bolded (white on mine); and opposite if headed to the right.
At the 2 mile distance, I got a correct JCV full screen (2 lanes continuing on the freeway and the ramp on the right side). After 3 tenths of a mile more, the LA returned and was still incorrect - staying that way through the exit.
Need some different GPS models

Thanks rame1012 and Jgermann for confirming the 765T,
We need some other simulation volunteers with different models to test this and post their results. This problem does appear to be model specific.
With very little effort I have found 3 more exits off I 79 in Western PA traveling north which have incorrect LA for the exit. The incorrect LAs all appear at exits that have a 2nd LA on the exit ramp. The incorrect LA is actually the 2nd LA for the ramp.

Some places get fixed with each update, others not
My LA odd error in this thread was not fixed yet. Did anyone else get their error fixed??
Yes, I ran a simulation of a route including an exit ramp that gave wrong LA directions with the previous map. At least in this one simulation of one exit ramp, the new 2012.40 gives me correct LA arrows now.
Yes, I have noticed that with 2012.40 that some exits and intersections that used to have this lane assist problem no longer have it, but I now notice that this issue happens in places where it didn't have it before. So we've really made no progress with the issue.

FINALLy Fixed!
With the 2013.20 map update the odd lane assist error is finally fixed along the I-79 exits in western PA. I can finally get in the right lane before my exit!

Lane Assist Issues
I too have been experiencing intermittent lane assist issues as described above after a recent map update to 2012.20 Europe on my nuvi 3760.
After significant stuffing about I found that new freshly calculated routes would work fine however, old saved routes would not display lane assist or junction views.
This is my work around...
1. Go to: Where To? -> Trip Planner
2. Select: An old route
3. Select: Menu -> Edit Destinations
4. Select: Save
This will cause the route to be recalculated, when running through the route next time you should have Lane Assist and Junction View.
Works for me, though your mileage may vary.
