Nuvi 760 4.6 firmware

 

Has anyone had any problems with the 760 voice stuttering with the new 4.6 firmware upgrade? It was pretty bad yesterday. I didn't have the problem before the upgrade. I applied the upgrade again and it still does it.

Can the previous firmware 4.2 be applied?

Nuvi 710 4.6 stuttering gone

Having read all the posts here I also found that the stuttering went away when I use the 2D track up map.

However, on going back to the 3D map after a few days the stuttering had also stopped for this view.

Not sure why this might be the case, but am happy for now!

Do you or did you have the voice lag issue as well?

I had stuttering problems. I

I had stuttering problems.
I updated the firmware and it went away.
I installed 4.6 and the stuttering returned.

voice stutter

so frustrating when u apply a new update or firmware and it messes things up!!

Stuttering bad

I find this site very helpful to all levels of users and see most everyone loves their Garmin, unfortunately, I cannot say the same but that's another chapter in the book. I did not experience any stuttering on all 3 modes after I upgraded to 4.6. However, after I upgraded Jill's voice to the latest version 1.80 or 1.90 only 2 days ago, i begin to experience bad stuttering in Track Up mode. when i switched to 3D the voice was back to normal.

Just my 2 cents on this issue.
Thanks for reading.

Why upgrade?

If I remember correctly from my working on BIOS updates on motherboards, motherboard manufacturers always recommend against upgrading your BIOS if your system is working correctly.

Why wouldn't the same philosoph apply to Garmin? If your system is working fine, leave it alone. Garmin has time and time again proved that it will not make your system better with each upgrade, but rather worse.

Just my two cents after surviving the last fiasco.

As if you have a choice. I just bought mine with firmware 4.5 and it had to be upgrade to 4.6 to register the unit. I wish I had a choice so I can decide on my own. My fault I didn't know how to backup previous firmware. I have not played around long enough with previous firmware to notice the difference. My stutter problem is related to bluetooth usage but only sometimes. It lags when I play MP3. My guess is, it just overload little bit and is normal?

This site contains the files from all of the "updates" if you want to load an earlier version onto your unit:

Good luck. I'm still on 4.2 and refuse to update my unit for now.

4.60 version is the best and most trouble free yet on my 760

I have run every firmware version on my 760 since the early 2xx firmware versions and the latest 4.60 version is the best and most trouble free yet. The only thing I have been able to find is that when you try to use the language tranlation mode and have it speak it a notice comes up about being unable to load voice file.

language guide not working

I have the same problem . I contacted garmin and the told me to send it back .when i got the new one back it did the same thing . the language guide work with software version 4.5 ,but when i regestered it at garmin.com you have to agree to upgrade to 4.6 , now the language guide does not work .the english will work but the other language gives an error UNABLE TO LOAD LANGUAGE .I searched other forums and they were right its the 4.6 version , now i need to roll back to 4.5 or wait until they come out with a fix.I think i'll wait because i doubt i'll ever need the language guide but it was cool to have . I wasted 10 dollars shipping and 2 weeks sending it back to garmin for nothing.everthing else works fine.

I have an occasional stutter

I have an occasional stutter with my 780 since the update.

New Firmware?

I got my 760 from Costco with firmware v4.1 and the stutter and lag were terrible, missed turns all the time. Based on the comments here and at GPSPassion i refused to update to v4.6 and instead loaded v4.2 from the "perri" site, which seems to have fixed the stutter and lag but there are apparently other issues on POI's and route optimizing which 4.2 does not fix.

Have any of the people who've actually spoken to Garmin heard if there are further firmware upgrades in the pipeline? I still have 60 days to take this back to Costco if they can't fix the issues by then! The Costco units seem to be all
"nuvi 760 S M V3 iNAND2 2GB"
on the software version, and are considerably cheaper than the original 760 prices. I think this means the Mediatek chipset rather than the Sirf chipset and I suspect they may have cut corners on other hardware items to drop the price.

Can anyone with the original Sirf chipset (nuvi 760 S S" ?) units confirm if these firmwares have problems with lag, stutter, etc?

Sams Club Model

I bought mine at Sams club around Christmas this year.
"nuvi 750 S M V3 iNAND2 2GB" SW 4.6

I have noticed just a little bit of stuttering since the last update.

It would be interesting to know each of the system characteristics for each of those that have the stuttering issue with v4.6 installed; system most loaded down or free. For example:

-Driving a route
-8GB SDHC (60% full capacity) playing MP3 through the audio out via cable to my car stereo
- Map draw set to max resolution (map redraw consistent with actual location)
- Bluetooth enabled and paired with my phone. (while on a call)

I have no stuttering when I have my 760 running with all the convenient features running as stated above. I purposely did this to see if I can get mine to stutter to try and offer some insight to this discussion, but to no avail.

There are so many plausible internal and external variables that could factor into this and it would be good to begin to isolate some of the common ones.

@jrozsnaki I see you have

@jrozsnaki

I see you have one of the original "nuvi 760 S S" units, with what looks like a V7 motherboard. Was this unit bought recently or is it one of the original 760 units?

My concern is that there seem to have been significant hardware changes between versions and this smells a little like "bait & switch". Put out a good initial version, get the plaudits, and then change production to lesser quality hardware to enable a price drop while still retaining the reputation of the original units?

Maybe I'm over cynical, but based on experience I don't put much past US marketroids.

SW Ver

mine - SW ver 4.60 nuvi 760 S2 M V3 iNAND2 2GB. no wonder it was so cheap. how big of difference is the S and M chipset?

i also have langquage guide loading problem. that sucks. other then that no real problem.

OK, another variation.

OK, another variation. Mine's
SW Version 4.2 nuvi 760 S M V3 iNAND 2GB

Wonder what the "S2" means?

I think the difference between the S and the M chips maybe that the first is Sirf and the second Mediatek GPS chips. From what I've read the Mediatek is a good GPS chip also, but the question would be what else changed on the motherboard from the "S S V7" to the "S M V3" - processor, ram speed, I/O functions, voice processing etc.?

Garmin won't tell anyone so the only way to judge really is by the effective result of the different versions. I hate this. I know every single component in my PC and what the relative worth/speed/efficiency of those components are. Wish we could learn the same about a product they're selling for the same price as a decent netbook.

Garmin started to make the change last summer away from Sirf

I think that Garmin started to make the change last summer away from the Sirf chipset was because of the legal and financial problems that Sirf is having and they could no longer continue to be sure that they would get the needed chips.

They not only released all their new GPS models with the "M" chip but even changed the current production models at that time in the mid production run like the 760 to the "M" chip.

Mine is still ver3.0

Any reason to update to 4.60? Mine still has ver3.0

No stutter, but...

It doesn't appear to have helped with the slow boot times either. Ever since I loaded 4.2, it takes longer to get to the ready screen.

OK, read it. Based on that Garmin seem to have changed both the GPS chip and probably the screen. Your guess is as good as mine as to what else was changed under the hood. I find it interesting that the models that don't seem to have problems with the current firmware stuttering, lagging, etc. seem to be the original hardware versions.

Bottom line appears to be that if you're reading a review of a 760 written before last summer then don't expect it to apply to a unit you're going to buy now. Different (lower quality?) hardware, buggy firmware.

I recognize that the price I paid was considerably less than the original price, but it really ticks me off that what I'm getting for it does appear to be a "bait & switch" product. If they'd offered it as a 760M then I'd have no problem, offering it as a straight 760 and relying on the reputation of the original model while substituting hardware strikes me as at least unethical, if not downright dishonest.

Well, what goes around comes around. It'll be interesting to see where that business model takes them in the current economic climate. I'm willing to be bet there are a few thousand less technical users out there who are very unhappy with their lagging stuttering Garmins right now and have no idea why or how to try to fix it. I know that if I didn't visit forums like this and just relied on the out of the box performance of the one I got it'd be back on Costco's shelves by now!

Stick with v3.x version

I think the one payment lifetime traffic option may require a later firmware, don't know for sure but seem to recall reading it somewhere - GPSPassion maybe? Other than that everything I've read says if you're lucky enough to have a v3.x firmware then stick with like glue! If you have to upgrade other items then there are some posts on GPSPassion about how to upgrade other items without upgrading the firmware. Look for posts by SergZak on the topic, but be careful - apparently if you upgrade to a v4.x version and then try to downgrade back to a v3.x version you lose Bluetooth functionality permanently!

ok i notice little bit

ok i notice little bit stuttering when using TTS voice. just a little, not enough to be bother.

i agree with 'gpsaccount'. it's like buying fake ferrari. smile

Fakes

I had one of the better (early) 760 models then bought a 750 in December from Costco. It stunk! I returned it. It took forever to load about half the time, gave bad routes and the screen was not as good. It was dim. They really cheapened the product. I going to try a small 260 and see how that goes. If it is bad, I'll try TomTom. Our 350 works fine but I need one without the antenna for my mount position.

760 Further testing

Well, I took a leaf out of an earlier post and stress tested it. 8GB SDHC card full of mp3's, Bluetooth on, traffic on. Operating with the 4.2 firmware from perry's site.

It now manages to tell me where I'm supposed to turn before I get there, rather than the 50 yards after the turn that it was using before, but it either thinks I'm driving at 10 mph or have the reflexes of a cat because the warning usually arrives about 20 yards before the turn, rather than a more reasonable distance to allow for indicating, lane movement etc. Also I don't seem to be getting any of the "keep right" etc. directions that I recall from my wife's 250. Still some occasional stutter, but more often clipping of phrases e.g. "One point t" rather than "One point two"

Net result - if you rely only on the spoken directions you can be in the left hand lane of a two lane carriageway with about 20 yards warning to indicate, check your mirror, check your shoulder and then change lanes and turn. Not really what I consider to be safe driving habits. Alternatively you can keep taking your eye off the road and checking the display, which I bought the TTS to avoid.

Haven't tried the route optimization yet, though I will be needing it this summer for touring purposes (said to be fixed in v4.6 - at the expense of rebreaking the stutter problem), and can't make head or tail of the currency converter. Tried to reset the GBP, USD, CAD and EUR rates in preparation for the summer and it's totally screwed - at one point it was telling me 1 GBP = 0.59 GBP ! Have also heard that the Language Guide doesn't work on v4.6 so I might have to revert to my schoolboy French, which means I'll probably die of starvation or dehydration! wink

Oh well, 50 days to Costco return date and counting, if a working firmware doesn't arrive before then. Is there anyone who can recommend a particular TomTom product that's equivalent?

Costco does not have a date-limited return policy for GPS. I returned one 6-months after I purchased it.

Not me!

No problems here yet! Will keep an ear out though. Thanks for the info.

Blue line through middle of route

Has anybody noticed a blue line going through the middle of the route they are on? I noticed it once I updated to 4.6. It does not appear all the time, but almost seems like it's showing the last route I took, when I am close to the same roads.

You have "Show Tracks" turned on. You need to go into the setup menu and turn Track Display from Show to Hide.

No Stuttering

I've been using my GPS driving into Boston for the last couple of days and other than the taking for ever to locate a satellite (coming out of the parking garage) I didn't experience any stuttering.

It was a bit confused although today in trying to find the ramp to I-93 South around Kneeland Street. It kept recalculating even though I was on the right route.

New Firmware?

Does anyone know if Garmin will ever release a new version of the firmware thats free of voice lag, stutter, and various other bugs reported on these forums?

No Problems with my nuvi 760

After waiting for over a month before jumping in the updating circle of fire, I did so a couple of weeks ago. I used my nuvi 760 all last week getting in and out of Boston and experienced none of the problems listed here.

It did take a long time to get a satellite signal in downtown Boston coming out of an underground parking garage, and got confused while riding on one of the ramps to I-93 South, but there was no lag and no state-te-tte-ring.

Go figure. My unit was adversely affected with the bad update two updates ago although.

Voice lag stutter

Well mine is a 4.60 running on a 750 and I occasionally get stutter. It seems to happen randomly and "I think" it's only on 2-D map display.

The Short Answer:

Esteban4u wrote:

NO.

The Long Answer: Manufacturers are asked to do so many different things with their units that oday's software code is so complex and convulated I am surprised it even works at all. The best Garmin can do is make sure that units do not update automatically via webupdater and take the MB manufacturers advise, "If your System is working okay, you do not need to update your BIOS".

Just my 2 cents.

This happened to me yesterday

I interrupted the startup and it lost the voice setting. I didn't realize what I had done until reading this. Glad I know what happened now and how to avoid it.

Still, I wish my 760 wouldn't take so long to start up. I like to use the trip odometer and have to choose between waiting for the startup to complete or having the odometer be inaccurate because I'm moving before it's found the satellites.

No lag or stutter, really?

Its possible you're not experiencing the issues mentioned in these forums because of the hardware revision of your particular 760. I believe that Nuvi 760's that were purchased before the summer of '08 have different PCB version than those purchased after that summer. Mine is a version 3 I think. I got it from the diagnostic mode you can get into by holding down the battery icon on the Nuvi 760 screen. I get out of the diagnostic by going to "Exit" then turning the power off on the unit. In the case of my unit, the line at the top of the diagnostic screen reads: "SW Ver 4.60 nuvi 760 S2 M V3 iNAND2 2GB". What does yours reads?

No stutters with PCB V7

Mine is "SW Ver 4.60 nuvi 760 S S V7 iNAND2 2GB". The following screen shows "PCB Version 7". Purchased mid-June 2008 and it came with firmware ?2.9? and 2008 maps. I upgraded the maps and firmware immediately. I have no stutters with 4.60. I did have stutters with one or more of the early firmwares but sometime after 4.x series was released, the stutters went away.

I bought mine last June from Costco when they were running their Father's Day special.

gpsaccount,

Sorry for the delay - I bought my unit in early June of 2008; had v2.9 installed and I was forced to update to v3.0. The date of manufacture is unknown. After 4.6, I am very pleased with it. Could be as you say or to improve the bottom line in a cost reduction effort, as the competition in the GPSr industry was tightning up.

Hi, no problem on the reply, I've been playing on my own and researching around the net. Looks like you lucked out and got one of the last "S S" units. There does appear to be a pattern that the "S S" units work great and it's the "S M" units that have the problems. Whether that's due to the "M"ediatek GPS chip or other hardware changes I don't know. Other reports on the Mediatek chip seem to be positive so it could be the PCB changes that affect it.

I managed to register without updating the firmware and it's still usable so far, though not stellar. I'm going to talk to Garmin CS this month and see if I can get some more info and inquire if there is another firmware update in the pipeline. I'm still in two minds about keeping it as the instructions are better, though still a bit too late for what I would consider adequate turn warning, and the options I seem to have at the moment are:

Keep v4.2 - lag and stutter more or less gone but still late warnings, trip optimization broken, currency converter broken.

Install v4.6 - get stutter back (and maybe lag), language guide broken, currency converter _still_ broken.

Buy a map, cheap calculator and language dictionary: and save $300! wink

I guess I'll bite the bullet and try v4.6 and see what happens, time is running out.

On a side note - if anyone wants to register _without_ having to upgrade the firmware it's pretty easy.

In the Garmin folder on the unit is a file called "GarminDevice.xml". Open that file in Notepad, on the second line is:

[SoftwareVersion]420[/SoftwareVersion]

just change that to:

[SoftwareVersion]480[/SoftwareVersion]

and save it back to the unit (after making a backup if you're sensible). Now when you go to the registration process it won't force you to update the firmware.

(Note: Brackets above are actually "greater than", "less than" signs in the file, but that affects the formatting in the post here.)
