Nuve 780 Freezing - Always at the same location

 

After the last NuMaps update, my 780 started freezing every afternoon as I am about to turn onto the freeway (for the AZ locals, US10 and 40th Street)

My MSN subscription expired at about the same time, I am not sure whether this could be a cause or not, and until I figure this out, don't want to subscribe just yet.

I sent Garmin a support request. They had me reload the software and perform a device reset.

It froze again at the exact same spot.

Garmin responded today with this below. Has anyone had similar issues and recommendations ?

"Thank you for contacting Garmin International.

Andre, I will be happy to help you. If you did all the steps and the unit works fine except for in that stretch of road or area, it might be something with the satellite and some buildings or maybe some ground satellites in that area. Unfortunately other than reporting it to our map company, there isn't a fix for that stretch of road as of right now. I will report it to them, and our engineers, so they can look into it. Please let me know if anything else we can do for you in the future. Have a good day. "

You are NOT alone!

cool
This is a PROBLEM with the update in ver 4.90 as it is unstable... The same problem has occurred in both my units when ver 4.90 is used. if you want to fix the problem then you will need to go back to ver 4.80...
4.80 is stable and will not give you any freeze ups or locks. I have learned not to update both my units until I test one or I get feedback from members of this site on the new update. "Lesson Learned" and a bit of advice to you.... DON'T be soo quick to update or install a NEW VERSION until you get some feedback here on this site. You can get 4.80 from the garmin site or I can get it to you if needed.

YOU HAVE A GOOD UNIT WITH A BAD UPDATE!!!

.

Please note that if you do decide to downgrade, you should follow up and send Garmin the results of your testing.

I strongly recommend that you try this, if for no other reason than to have the appropriate information to help Garmin realize if they have a problem or if it is truly due to external issues.

Based on their reply to you, it is clear that they are playing the age-old game of finger-pointing. The question is whether this is justified or not. Altogether too many times Garmin support people talk through their hats.

The problem is that, unless someone like you follows up and spends the time to actually do the research; downgrading and seeing if that solves the problem and then reports back to them with a clear and unequivocal report - and follows it up, then Garmin support will continue to ignore their bugs and blame the maps, the government, the weather, the locale and everything else in the world.

On the other hand, if it does NOT solve the problem, you can at least take comfort in the knowledge that you will have done what you can to validate the claim, which is also an important function.

In either case, letting Garmin know the results is an important component to the testing.

Garmin's response seems like BS to me

I also think you likely have a problem with the 4.90 version. Backversioning and seeing if the problem persists would be a super idea as noted above.

I cannot see anyway you are going to lose satelite lock at that exact same spot every time you go by unless it truly is some sort of canyon of concrete.

BS from Garmin I am sure.

Simulation.

Does the problem occur when you navigate the route in simulation mode? If so, you might want to post start and stop points so others can test the route with different models / software versions / map versions and help you narrow the problem down. The more specific you can be in the information you provide to Garmin, the better the chance they will address it with a future update.

How do you think Google gets those street view pictures?

..

Perhaps the Garemin "tech" (perhaps more appropriately, "call taker") was thinking about a Differential Correction GPS station - but those do not deliver data over GPS frequencies.

XM and Sirius (now merged) use 'Ground Satellites' to improve their signal penetration in major urban centers..

There are MANY other owners who've encountered this sort of problem after an update. Personally I'm very happy on how my unit functions and have never updated the software.

Thanks

Thanks for the follow up. I also suspected the update to be the problem.

I will run it in simulation mode and post my findings back.

I am requesting a downgrade from them now so that I have some record on file with Garmin.

Lesson however has been learnt. I just figured that now that I am paying for the maps, I might just as well download them when they become available.

Interesting that others are having similar issues.

Odd behavior on Nuvi 760

After the last map update and firmware update, my 760 exhibited several strange behaviors. I finally resorted to a hard reset. Since that time I have no problems. You might try a hard reset before reverting to an older version of the firmware.

Nuvi 750 Freezing with Proximity Alerts

Since updating my 750 to version 4.90 and doing a hard reset, the nuvi locked up in the same location on two different occasions. I tried driving the same route a third time with Proximity Alerts turned off. The nuvi did not lock up this time!! (The lock up location was in the range of a Proximity Alert.)

Do others with lock up problems use Proximity Alerts??

I did the hard reset as per

I did the hard reset as per the the instructions from Garmin after reloading the software.

I also ran the simulation mode for my route and the unit froze at the same point it does while driving.

I also drove a route, that follows along the same street but instead of going onto the freeway, my destination just lead my down this road and no problems. I turned around, went back to my starting point and set my home destination and it froze.

I guess from this one could assume that there is an issue with the road maps. Just Friday however, I experienced two more freezes but this time at other locations, one I drive each day and the other a new location never driven before.

Here is the route that freezes if anyone cares to test: (Abbreviated origin and destination points)
start N33.40532 W111.99539 nav to N33.41084 W111.99084
it crashes at about N33.40951 W111.99532

The following route did not crash, even though it passes over N33.40951 W111.99532 where the GPS usually crashes.

Thanks

start N33.40532 W111.99539 nav to N33.41685 W111.99544

Opened another trouble

Opened another trouble ticket with Garmin today. They recommended I upgrade to 2010.40

Downloading now. I wonder if this will cure my problems.....

My old StreetPilot used to freeze like that

...0n the main road through the Great Smoky Mountains (US441, I think) right when you cross between NC and TN. I told Garmin about it but nothing, to my knowledge, was ever done about it. I'd have to flip the thing off, let it sit for a min, and then flip it back on and all was well.

For improvements to their firmware: You used to be able to use software on your PC to load/update the firmware. I really prefer that method to the constant checking to see if you have it plugged in method now. Anyway, years back they included a release that changed traffic from being shown on the main map page to only showing it on the traffic map page unless it's currently on your route. I kind of preferred to see it on the main map page (it would just highlight the roads as normal). They said that they had improved it but I really would have preferred the option so that I could flip it on or flip it off. The fix was to go back and get the earlier firmware and install it.

Well, .40 has the exact same

Well, .40 has the exact same problems.

In fact, I am seeing some weird routing where it wants me to jump off freeway, detour and then get back on the same freeway again !

I am going to bug them again, and again, and again until they resolve.

Using Proximity Alerts?

2010.20

Had a similar problem in my area. It would plot the route just fine but when you reached one intersection where you were to get on the Interstate it would always tell me "I think I'm lost. Let me stop and ask directions." (TTS editor is so much fun!) It was corrected in the dot 30 update and I haven't checked the dot 40.

ɐ‾nsǝɹ Just one click away from the end of the Internet

I had my 855 freeze at Alert POI locations

I was using poi.gpi file(s) created for my old 255w with wav sound files. I decided to try mp3 files since my new 855 had a mp3 player. That fixed my freezing problem.

I also downloaded a tourguide poi.gpi file from a website for a NC trip. It froze my 855 several times. I had to turn off tourguides to make 855 function. I assume it was created with wav files also.

I don't know if this is related, but hope it helps.

I am not 100% sure how to answer this but I am using POI Factory files for traffic and speed cameras which includes alerts, so I guess I am using proximity alerts.

There are however no proximity alerts at the place it most frequently freezes.

RMA

Garmin has finally given up and gave me an RMA. I will be returning the unit and see what they replace it with.

There does however seem to be something funky with the road maps.

From my work, it usually routes me down 40th street onto the US 60 freeway all the way home.

Sometimes however it will route me on the surface streets to connect with US 60 but totally in the opposite direction of the normal route of travel.

The directions settings are always the same - faster time with no avoidances set.

When I zoom right in, it is strange that the icon sometimes wiggles on a perfectly straight road. I am thinking that there are some bad connections on the street level.

I get funky routing from

I get funky routing from time to time.

If I set the destination for my daughter's home from my home it will miss the obvious ramp onto the freeway and route me down the opposite way on the freeway to the next exit, have me turn around there, and then proceed back on the freeway (the correct way) as normal. If I go anywhere else in that general direction it seems to see the the obvious ramp and takes the obvious path.

I figure it's a deal with the routing algorithm.

There's a section in St Louis where the obvious path is to stay on the freeway but it will do everything but that. It's like 5 miles of freeway are there on the map (on screen) but it doesn't think it's possible for it to use that section. Really weird.

I don't think I've had a freeze up with the current unit. Not at the same place where it was happening before.

Map errors?

Brad, these sound like map errors rather than routing algorithm problems. Do you have map version 2010.40? I know that there was an error introduced in that version for St. Louis. It is discussed in other threads on this forum.

Just got my unit back

So Garmin sent me a replacement.

There are at least three Lifetime map updates reported for my device at MyGarmin.

Before updating, I am first going to go drive the routes that gave me trouble in the past and see if it freezes up again.

Still freezing

So today it froze again at the regular spot !!!!!

Still had the NT 2009 MAP on it as it came back from Garmin.

There is a POI camera point in the immediate proximity of where the device freezes. Could this be part of the problem ?

Similar Problem.

I had a similar problem on my 750. The 750 would lock up at the same point as I approached an alert point. I turned off the proximity alert and have not had the problem since.

My 855 would lock up when I

My 855 would lock up when I passed alert locations. I was using custom poi files created with wav sound files for my old 255W. I recreated using mp3 files and that fixed my problem. Not sure about 750 but you may want to give it a try.

I have a suspicion that the POI's had something to do with it, but all is well now.

Ah, thanks. I have last years map (2010.10). It's in my in-dash unit so I can't do the numaps lifetime. When the new SD Card maps come out I'll update the Kenwood/Garmin unit.

Try removing all icon files

I didn't see your post before, but I have one about Nuvi freezing at the same spot. Don't know how to ref it. I found out that the icon for ExxonMobil was causing mine to freeze. It was an old file and I suspect that there are more that are bad. A new icon was created for this file and it ran perfectly. The original icon was slightly larger than the 24 x 24 pixels as well as being written for an older system. It is worth a try anyway.

Hi, Is there any chance of sending me the downgrade or tell me exactly where to get it as i have a problem with the new software version.

Icon or Sound file

It is too bad that returning the nuvi to Garmin did not help, but it shows it is operating properly.

When you approach any POI, an icon or sound file is processed. I agree with CurtHinson. If something is wrong with the icon or sound file, that could be the problem.

The ExxonMobil thread finally concluded that the icon was bigger than 24 x 24 pixels, and that was the only problem. There was nothing wrong with maps or updates.

My 760 has fully updated maps and firmware and operates flawlessly. My POI icons and sound files just happen to be compatible with the operating system of the nuvi.

Nuve 780 Freezing - Always at the same location

Hello!

I have had the same problem, with a certain speed camera. But only in Map mode "dirving direction up". When I use 3D it don't freeze. Since yesterday I downgraded to 4.80 and have no problem

BWi

Is an icon displayed? and check the Poi file

Check the screen in both map modes, driving-direction-up or 3D, to see whether an icon is displayed in one mode and not the other. This would explain why the map mode has something to do with it.

If an icon is displayed, temporarily delete the icon from your POI folder and reload the POIs. Then check to see whether the nuvi still locks up at that location without any icons being processed. Icon size is limited to 24 x 24 pixels. A bigger one causes the nuvi to lock up. It is possible that a bad sound file could cause a lockup in the same manner.

Also, what about the integrity of the POI file? Was it downloaded from Poi Factory? Was it edited in any way? Open the file on your PC in Notepad and inspect the one line of the text file for that speed camera for defects. See:

http://www.poi-factory.com/garmin-csv-file-format

My nuvi 760 is fully updated and does not lock up, but I don't have icons loaded for red light and speed cameras.

dobs108 smile

Nüvi 780 Freezing - Always at the same location

Thank you dobs108!

I removed the icon in the Camera File. Now everything works (also with 4.90).

A year ago I mailed Garmin and we found that i was depending on a certain speed camera and the display mode. We disn't solve that it was the icon.

BWi

Thanks to CurtHinson!

Nüvi 7X0 Freezing - Always at the same location

I tested with different icon size. It works down to 17x17 pixels. As soon as I try with 16x16 pixels or lower it freezes.

Fascinating

If this is true, you should contact Garmin to let them know of this bug. The more details you can give the better.

17 X 17 is pretty small and 24 X 24 is not big enough in my opinion.

üvi 7X0 Freezing - Always at the same location

I have already done that. It is funny that it was just the icon for speedcams I made 16x16, for other icons I use 22x22.

780 Freezing

Hmm.. This is interesting.

I have a 780 and haven't noticed any of this yet.

But maybe I'll force some of these settings etc into the unbti and see what happens.

Garmin hasn't put out any firmware updates for this unit for a while. Maybe they will if these problems are reported.

I think the 780 doesn't have its own firmware updates. It uses updates for the 760. Run WebUpdater to find out. My policy is to keep the nuvi fully updated.

this happened to my nuvi 750 when I saved 2 addresses and did not enter names. the gps froze after several seconds. sequence of events:
1. I hit "where to" button.
2. I entered address.
3. gps gave me 2 addresses, one is avenue , other one is street.
4. I hit save on first address, I did not enter a name.
5. I hit the back button.
6. I hit save on second address, I did not enter a name.
7. I hit "where to" button. I hit "recently found", I chose first address.
8. gps calculated the route, then froze after a few seconds.
9. I restarted the gps , same thing, calculated the route then froze after several seconds.
I solved the issue by doing a hard reset. this erased the "recently found" and "favorites" info.
nuvi 750 works fine now.
