Garmin nuvi 350 longer and longer time...

 

Recently my Garmin nuvi 350 is stuck on "Acquiring Satelites" for a long, long time... Sometimes even 1/2 hour or more.

I'm running the latest (4.60) software version on the device.

I did the following things to try to solve the problem:

  • Power Cycle (still no satelites)
  • Reset (still no satelites)
  • Cleanup (still no satelites)
  • Answered yes on the question "Have you moved hundreds of miles" -- got the satelites, but after trying to find them for 2-3 minutes.

I think this is abnormal behavior. Did anyone experience anything like that?

It happened to me too!

Hi,
I experienced a similar problem to what you're having. It happened once so far. Unfortunately, I didn't get a concrete answer on how to fix this. I was told it might be my location or time of day. If your car is moving, it might have problems acquiring a signal as well.

Maybe someone with more experience and knowledge can help us out.

Same Thing Here in Atlanta

It takes at least 5-10 minutes when "Cold"

- however, if I turn it back on again (Within 1hr or so) it aquires quickly - under 2 minutes

I did download the latest firmware about 3 months ago..

i had a similar problem that it couldn't find any satellites.. i was lucky enough to be able to get out of that freeze by powering off and then on. If i find anything i'll let you know.

If you're moving hundreds of miles, it's...

...not abnormal. Different satellites are visible in different parts of the sky, and when you move a long distance, the GPS has to figure out where to look.

It also has to receive what is called ephemeris data, which each satellite sends, as to its orbit. Such data is only good for a few hours, and sending it takes about 30". Since you need 4 satellites to get a good reading, getting an update can take 2 minutes.

I think we all suffer from the misperception that everything electronic should give us instantaneous responsiveness. When you deal with the complexity of something like GPS, with multiple satellites, and needing precision of signals to make the precise calculations of where we are on a spot of the earth, you have to tolerate a handful of minutes being required to do it right.

Long lock times

Based on my experience with the Nuvi 660 I would say taking 1/2 hour to get a satellite lock means there is a problem. I have flown several times recently from Michigan to LA and SF and the GPS locks in under 4 minutes at the destination. I have never had to wait more than 4 minutes for a lock on the 660 regardless of how far I have moved. I have also had similar experiences with the GM OnStar system and hand helds locking within 4-5 minutes. The only times I have seen extended lock times on the handheld is when there is an obstructed view of the sky. Assuming no obstructions it might be worth talking with Garmin about.

Not moving hundreds of miles...

No I have not moved hundreds of miles and no, I would not expect instantaneous lock. I am an electronics engineer and know how GPS satellites and the devices work. I am a tolerant man, but read my message carefully... 1/2 hour or more... Come on... Do you think I should be waiting that long?

Here is the situation again... I am turning on the nuvi 350 and I am on my way, but slowly... I have not run the device for more than 2 days. Now I know for sure that the satellites are not geo-stationary and they would be more difficult to lock on, but I still don't accept the fact that for more than 1/2 hour the device could not lock onto them. I would tolerate it to some extend, but when it is taking the same time as my short trip and I have to find my way with an atlas... How would you feel about this?

I live in a very "radio busy" region but I have no obstructions of large proportions where I live. Could it be the interference? Who knows? It could be. I also experienced some interesting moments of loss of satellite reception on the highway which had a clear view of the sky. There were some overhead bridges, but I was moving with 80 mph, so I would not think them as obstructions.

All I know is that there are times when I really need this little devil and it is not playing by the rules of engagement smile.

I have found it locks much quicker first time I turn it on after a day or two if I remain stationary until it gets a lock, and my previous 350 and now my 660 lock in at most 2 to 3 minutes

A half hour to get a lock is a bit much. I'd call Garmin support.

Master reset of nuvi...

Folks,

I called Garmin twice regarding the problem, that started this thread and here is what they answered (second time):

Do a master reset (not as in the manual, but what we are going to tell you). The master reset is done by holding the left lower corner of the screen while powering the unit up. Not the upper right, which is clearing the user data.

Did anyone know how to do that? Am I the only dummy here?

--

Reset

I assume they mean to push on the very lower-left corner of the screen with the thumb (or finger of one hand) while pushing the power button with the other hand. Hold down on the screen until the unit is completely powered up.

When you do the master reset, you clear all data (except custom pois and your password). When your GPSr starts up, it will ask you for your location, etc., just as when you first obtained the unit. It will also lose your favorites. I move mine with Mapquest onto my PC so I can reload them.

Garmin StreetPilot c530, Mapsource

Same problem

I live in Curacao, Netherlands Antilles.
Just received my Nuvi 350, turned it on, immediate reception. But later at night, when I was testing it I lost signal. That was yesterday. Till now almost 24 hours later can not lock.
I ordered a high gain antenna on E-Bay, will see if it works better when it arrives.
I bought this thing especially to use in Las Vegas and California, for my July visit. If it will keep having lock problem I'm ruined.

Sending it to Garmin for a fix...

Well... Folks...
The verdict was declared yesterday...
I am sending my nuvi 350 back to Garmin to service it. I stayed almost 2 hours on the phone with the tech guys and we tried all kinds of tricks and settings. No success, so they sent me and RMA email and this is the end of it for now.

I will be waiting for mine to come back (they said 10-15 days). So lets see how this case is going to be resolved.
If the outcome is not as expected, I'm going to go for a Tom-Tom next...

DOP

Dilution of precision (DOP) or Geometric Dilution of Precision (GDOP) is a GPS term used in geomatics engineering to describe the geometric strength of satellite configuration on GPS accuracy. When visible satellites are close together in the sky, the geometry is said to be weak and the DOP value is high; when far apart, the geometry is strong and the DOP value is low.

Thus a low DOP value represents a better GPS positional accuracy due to the wider angular separation between the satellites used to calculate a GPS unit's position.

The term can also be applied to other location systems that employ several geographical spaced sites.

Factors that affect the DOP are, besides the satellite orbits, the presence of obstructions which make it impossible to use satellites in certain sectors of the local sky. Especially in urban measurements, this may be limiting.

This situation happens twice a day. Each day at different times.

Doing surveying, I've had to wait in one spot for about an hour. Some days less. Look at your gps's accuracy. Some days it'll be 6-8 feet. Other days it'll be 34 or more feet. That's the DOP effect.

Solution? Patience

Hi, I had a similar problem with my nuvi 660 earlier this month. Garmin told me to do the same thing (the resets) and nothing was resolved. I sent my unit back and received another working unit from them about 2 weeks later. Evidently Garmin doesn't repair the device, they'll just replace it. Other nuvi owners that have gone down the same road have experienced the same thing.

DOP

Thanks EagleOne... Your knowledge is impressive. But it has no relation with a defective unit fix or replacement. So DOP in this case high or low would not affect the "not-working" state of mine smile

I wanna thank you though. One more piece of information, which gives me more clues on the GPS principles.

Cheers!

Yes. It did. I'm not that inside in the circuits, but I think there could have been a bad solder between the GPS internal antenna and the GPS chip itself.

I had the same problem with

I had the same problem with the 350. And I was not one thousand miles from where I turned off the GPS last. Turning it off then on solved it. I also noticed when the battery is low, getting a fix takes a little longer than usual.

I do not have the problem, but

I do not have the problem, but I noticed that my old C320 picks up signal faster than my latest Nuvi 350. C320 does no have SirF chip while Nuvi 350 does have. Not sure why my Nuvi is slower.

I also don't have the problem...

I've noticed that my Nuvi 350 acquires about twice as fast as my C330 or C550, and about four times as fast as my SP2730... Combine that with the full signal screen inside my house, and I'd have to say that if you're having acquisition take more than ~5 minutes with the N350 from a completely cold start, you're having problems that warrant a call to tech support.

i was told the following

i was told the following from Garmin Tech Support see below....since doing this it has helped but not much..........

Sometimes the almanac data that your nüvi stores for satellite acquisition becomes corrupted. This causes acquisition to become slow. To correct this we need to update your software and perform a master reset. This procedure will erase all user data.

To update your system software (firmware), download the WebUpdater on the following web page:

http://www8.garmin.com/support/download_details.jsp?id=931

After this program installs, your unit will need to be attached to the computer via the USB cable. The program should recognize the unit and you will just need to click next and follow the instructions to update your unit.

With your nüvi powered off, press and hold the lower left corner of the screen. Next, turn the power on. Continue to hold the screen until it asks if you really want to enter maintenance mode. Next, choose clear user data. The screen will flicker a bit and then start up like it did when it was first turned on. Follow the directions to set time and location. You will have to reacquire satellites by turning on your nüvi with the antenna up outside in full view of the sky. This one time acquisition may take up to 30 minutes.

Mine Too

My Nuvi has suddenly become slow to aquire sats even with the updated maps. I wonder if the Feds are messing with sat access?

I think it is BECAUSE of the

I think it is BECAUSE of the map update. it seems ppl are saying that after the update.

Nuvi 350 Sat Acquistion Time

My Nuvi 350 almost always acquires in less than aminute. Have you tried it outside and away from large buildings that might obstruct the satellite signal?

I done the reset, didn't

I done the reset on my Nuvi 660, didn't lose favorites, just user settings. It's still not getting the Sat's until I've drove 2-3 miles after overnight in the same spot.

Slow sat lock after Map Udate

I started reading this thread because my Nuvi 680 used to be very very fast to acquire a lock. But now in the same exact locations in the same weather conditions, I've noticed it being slower 2-3 minutes instead of 15-20 seconds. I think this began to occur just after I did the 2008 map update. But perhaps something is going on I don't have and scientific proof. Just that I noticed it was slowed and wondered why and saw this thread then thought back to the first time I remembered it being slow because I was late to get to some place I was counting on it to provide me directions. So has anyone else noticed a slow update after loading the new maps?

Lock time

I only have problems with long lock times if the Nuvi has been turned off for a number of days or I have traveled across the country and turned it on. It usually locks onto 10+ satellites within about 10 minutes after an incident like this.

Hi guys. i wrote this about

Hi guys. i wrote this about a month ago but haven't been here for a little while..........

..... have you noticed that if you do the free UPGRADE from the garmin site, it seems like after you do it, the nuvi takes a LONGER time to find the satilite signal then when it first came out the box. I'm on my second nuvi 350 the first one i had it for 2 months did the free upgrade (not to be confused with the map upgrade) it kept taking longer and longer to find the signal till it finally never ever found it. Luckly i bought it with the service plan from best buy and when i contacted garmin they told me send it back to them and just sit and wait. Well my 3rd sense kicked in and i took it back to best buy and they gave me a new one sealed in the box on the spot. ahhh no waiting from the mailman. but i did do the upgrade again and it takes longer then usuall to lock a signal. I'll see what happens when it finishes updating the maps.

i see you guys ran into the same problem i'm having. i thought the problem would get better after the 2008 map upgrade but nope it still takes a long time (compared to how quick it was when it came out the box) to lock a signal. With the old one that i returned i did all that resetting that they tell you to do. That don't work. hope they can solve this problem soon cause it is gettign really annoying.

maps and upgrades

Rated r, could you be more specific what exactly are you referring to as "free UPGRADE"? Are you talking about the firmware (unit software) or other upgrades?

My side of the story with waiting for Garmin is that after I sent the unit back, they sent me older (produced previously) unit of the same model. Now it is working fine and I happen to turn it on rarely, but it always acquires satellites in less than 2 min (most of the time less than 1 min) regardless how many miles I moved.

More importantly it is upgraded with the last unit software (4.60) right after I received it.

trees block signals.

When at my sister's camp in the adirondacks, it took forever to get a lock. And at home, I noticed a big difference when the trees leafed out this spring. If you live in a rural area or densely urban, expect signal blockouts.
Wit my handheld in the woods hiking, it can sometimes take a couple of hours to sync up.

In my case

there is a clear sky without any trees to block shy. The weather was sunny and very clear too. So in my case this isn't caused by obstruction.

Long time aquiring sats

I discovered that if I turn on the WAAS in my Nuvi 350, that I get much faster aquisition, especially inside a building.

I find it very interesting that tree cove blocks the signal. As a test yesterday, I turned on my NUVI 350 while on my way to work on the usual route.
I live in Queens NY, and travel on a road called Union Turnpike that runs next to Forrest Park. For a small section there is tree cover, I noticed that the accuracy went from 13 feet to 28 feet in a progression as I made my way through the tree covered area.

I find it quite surprising that the accuracy deteriorates so rapidly and to such a degree from minor tree cover.

I would make the assumption that this is due to an inexpensive electronic design and inexpensive components used in these units. I base this upon the fact that the armed services use GPS under much more severe conditions then just a few trees covering the receiver.

ETZVETANOV I'm talking about the firmware not the maps. both my 350's got ruined (i believe) after i installed the upgrades. I did get the 2008 maps but it still takes longer to lock a signal then when it came out the box.

what saved me from having to return it to garmin, is the fact that i took out a 4 year insurance from best buy when i bought it. any problems i have with it, they give me a new one on the spot. no waiting for the snail mail....... ;o)

Score... I think you have done the best so far, because now you will have a replacement whatever happens...

But about the firmware -- I believe it is good. But have in mind how sensitive the devices are. You might be running in the situation where each one of your nuvis is having the problem of low quality soldering, which causes oxidized contacts, especially of the internal antenna or the GPS chip itself not to work properly, thus causing the longer delay of acquiring the satellites.

But yes... it is good to have your protection in mind smile
This way you can also get updated maps for free smile

I had a Nuvi 350, had many

I had a Nuvi 350, had many issues with it, got it replaced twice by Garmin and still had the same problems. I was not even able to aquire a single satellite fix when I was in the basement of my home. From a cold start (outside in the clear) aquiring a signal was anywhere between 1 to 5 minutes while driving.

After finally giving up on Garmin and was desperate on finding something that would not let me down, I read up on LG's unit LN740.

With this unit, aquiring a satellite signal seems effortless. From a cold start, even in my basement, is ~38 seconds. From a cold start while driving is just the same....it still amazes me to this day on how fast and how accurate this unit really is. Although the Garmin unit had it's pros, it had it's cons as well.

I've looked at the whole picture and I am impressed with what LG has produced. Certainly they could have improved with a few items but they are indeed items I can live without or better yet, live with.

It happen to me on vacations

It happen to me on vacations and the signal never came back. Send it to repair. When they receive it it was working. They change the battery, wich made no sense but anyway. Got it back and 10 minutes later lost signal again. Send it back. Thay change the planer board. Did not work any better. They change the gps chips same thing. I send it back and appenrently it would be the (flap) the antenna that gets worn out by being open and close to many times. I had mine for 2 years and use it almost everyday since Im working on the road. It did a very good job until this break. I had a warranty so they change it for another one. Like you I did a cold reset a upgrade of every software but nothing solve the probleme. I had another GPS from nextar. Cheap thing but it gets the signal in less than 2minutes. So if you loose the signal with the 350 or the 370 which look the same and uses a flap as an antenna then get it fix. IT'S not a NORMAL situation.

+1

Our 350 is getting slower and slower. Twenty minutes to find satellites now. Our 265T takes 30 seconds to 2 minutes.

Maybe it's time to just get a newer model...

Eat at Joes.

There are posts about 350

There are posts about 350 problems acquiring satellites.

At work, a coworker bought an $12 external antenna. It did not correct the problem initially.

I did a reset of the unit with the external antenna connected and it started acquiring satellites again. It has only been a few days but hope it is a permanent fix.
