Update 4.10 for Nüvi 760

Thanks for the tip but unfortunately that won't work for me. I have never used an SD card in my Nuvi and there isn't one in there now. I am just hoping a language update will help me with this. This feels like Windows when I was perpetually hoping for that "magic upgrade" to address previous issues and not introduce new ones.

I'm going to wait as my 750 is working real fine with 3.1. I may update in 2 weeks or so, wait and see how you guys are doing.

Where would we be today if Christopher Columbus said "I'm going to hold off heading for America for a couple of weeks. There are storms, Indians, hurricanes, petulance and all other kinds of dangers out there right now"?

So because Columbus sailed to the new world I should take a chance and install a version with known issues? Like has been said many times previously "If it ain't broke, don't fix it" I'll pass on 3.0, 3.1, 4.0, and 4.1. I already bricked a 760 with 4.0 soooo.... Unless I can revert to a previous version, thanks, but no thanks

I don't think he got anything like he bargained for - wasn't he looking for a new route to Asia at the time, but came across some continent that wasn't mentioned in the documentation

I was fortunate enough to have been forwarned about 4.0 and did not download it, but despite that today my 750 locked up and will not restart even with a master reset. I have been told I have to return it, so I think after the update debacle along with this being the 2nd time I have had to send this unit back along with having to send my 350 back twice I am done with Garmin for good.

I propose that the reality for all this is that Garmin did not try to fix the voice delay. That was not on the schedule for this update. Probably never was. I believe it is possible that this update (4.1) was already done and in testing before 4.0 was released and most likely the next update is nearly done, if not already done and in testing. Any fixes to the 4.0 troubles MIGHT happen in the next release, but realistically may not happen til the one after that. This software is not the effort of a single individual and requires a plan to keep all the individual programmers together. If it were a single person, the program could be quickly adjusted to the real world performance issues. However, this is most likely a team of programmers. As it is, they have a plan to follow and if it is not followed they would not have a hope for this thing to work at all. As I mentioned before, it takes time and a fair amount of energy to change the direction of a large ship. There is probably a project schedule at Garmin that has all of the planned updates for the life of the 7x0 series and any bugs that crop up must be scheduled in with minimal interruption to the overall plan.

Meanwhile back at the ranch….

I have a 750 on 3.1 and two 760’s on 4.0. One of the 760’s is the one I purchased and updated to 4.0 and the other is one Garmin sent to me on an RMA for mine before I sent it. Unfortunately for me, the rebuilt unit from Garmin had 4.0 installed rather than 3.2 that others have mentioned. I was a bit flummoxed by that and decided to not return mine right away. I must admit that I am impressed that Garmin would do that before I sent mine in. However, to me it indicates that Garmin doesn’t quite get what the issue is. There are lots of possibilities, but only they know what is going on.

So…, I created my route to work in MapSource and loaded it to a SD card. I then copied the same file to another SD card and inserted one in each unit and imported the routes. I have documented this morning how 4.0 works on my 45 commute. Both my 760 and the rebuilt unit perform nearly identically with only minor variances in the instruction timing. Both are late by .1 to .2 at highway speeds through the countryside and give about ½ the final turn instructions in town after the turn is made. I plan to document the return trip this afternoon, update the rebuilt unit to 4.2 and then repeat the comparison on my next trip to work. However, I will also grab my wife’s 750 and have all three working. I should mention that the 750 and 760 were spot on to each other when they were both on 3.1. This should make for an interesting ride. If I can make this happen and I don’t crash , I’ll report the results as soon as I have them complied ( probably a day or two out).

I have the 760 and downloaded 4.1 and everything seems to work fine for me...

I have the 780 and downloaded 4.1 over my 4.0 and it ain't no better, it ain't no worse and it ain't no change. Still the 2 tenths lag and speech breakup. Will wait for 4.2.

Downloaded 4.1 over 4.0. I'm not seeing any issues with voice stutturing (using Oz's Karen) or turn direction lags on my one test drive. 0.1 mile warnings fire off around 500 feet before the turn which is near spot on. Just one person's experience, and YMMV of course.

It's got to be better than the gimped up version that is in there now (running 4.0)

I hope that they learned a lesson and ran it through its paces.

Updated 4 to 4.1 have my fingers crossed.

Just talked to Customer Support on unrelated issue and asked about 4.1 and was told they were getting lots of complaints on it today. Also asked about possible firmware updates to the 7xx series giving the them some of the new features from the 7x5T models and was told "Not at present , if it happens at all it would be awhile away".

It would be nice to get some of the new 7x5T features on my current 760 but most of the new features are going to be available on the new ones only because of some major hardware improvements not available in the current models. The new ones will have a much faster CPU, faster memory and 4 times faster screen refresh rate.

About the only thing we can expect on the 7xx series according to Garmin that is on the new series is the addition of "HotFix" support that will make for quicker sat acquisition. They already added it to the 8xx series with one of the Changes made in the recent firmware version 3.00 update where they added the HotFix support

Saw this posted on another website:

Hi guys, I took Jill for a full workout today using my nuvi/jill in the NYC, Philly and Jackson, NJ. Most of the lag is noticeable on the Highway and not too bad on city streets. Again, on the highway Jill stats .06miles when the screen shown 0.4miles. Screen is much smoother when she talks compared to version 4.00.

Final thoughts:
I’m not crazy about lag although this is a better upgrade then 4.0. I however will go back to 2.90. I just like things working as they should and 2.90 is just what I’m comfortable with.

Hope this help you all out.

My new 770 was shipped by Costco.com yesterday (Monday), I await its arrival, so I speak from total ignorance (soon to correct).

A tenth of a mile at 25mph calculates to about 15 seconds. Does this mean the voice comes out 15 seconds later than when it "should" have? Seems like voice would be useless a lot if not most of the time. Is it useful? (Nice thing about Costco is the ease of returning things to their store).

Everything seems to work just fine, except it inexplicably lost satellite reception for a second or two.

No Bluetooth issue, but never had one with the 750 anyhow.

Or had he said, "I'm going to wait for the next Garmin update."

I just used Nuvi 7xx 4.00 Firmware Fix found here to revert back to 2.90.
http://www.poi-factory.com/node/16877

thanks for the info

With 4.10 can you roll back to 2.9? And if you can, is 2.90 light years ahead of version 4.1?

Thanks,

"R"

Have any of those that have tried 4.1 checked to see if it still blocks out a rollbacks to 3.1?

I noticed you have the 760 which has bluetooth. As with version 4.0 if you roll back you will lose your bluetooth option.

My 750 has no bluetooth so I rolled back to 2.90 without any worries.

Yes sir, read my post above yours. However there is a way to roll back.

I do not think you would be gaining anything even if you could. As I recall the problems with the 3.10 and earlier firmware versions were more severe. There were frequent shutdowns, screen freezes and lock ups. Those problems appear to have been corrected in 4.10 and now the slight navigation anouncement lag seems pretty minor in comparison. I'm sure Garmin will work this problem out soon.

I don't find the "slight navigation announcement lag" to be minor. It makes me crazy and was really bad the other day in major traffic when I had to take and exit and IMMEDIATELY take another ramp. I was passing the ramp before it ever mentioned the thing. If I was one of those idiots who tried to compensate at the last minute I would have been in a pretty nasty accident. I went on past and had to deal with ugly traffic trying to get back to where I needed to go. The lag is dangerous.

The question at hand is how to make Garmin fix the problems that they created. I've come to the conclusion that the only way Garmin will respond quickly is if they are hit with a class action suit.

What do you think?

I'm thinking it goes back to Costco when it arrives and I start looking at Tomtom's.

Never thought I would say that. But I am tired of this crap with garmin. They should have had a recall on 7xx series. Look's like as long as they are collecting your money they don't care. Let see if they care if they start paying it out!

You didn't use any smileys, so I will assume you are serious. My experience with a class action is that you first have to show damage. Have you been refused a refund and or suitable replacement unit? A class action suit will take months or years to get to resolution; you are willing to go through this after giving them a whole 2 weeks to fix things? Finally, if you try to find a law firm who will file such a class action, I think you will find it impossible to do so, unless you pay for it.

Nuvi 760

Has anybody had issues with the FM transmitter since upgrading to 4.0 or 4.1? I use the FM all the time while traveling and have never had a problem prior to 4.0. Yesterday before updating to 4.1 I had the FM transmitter just stop working. Turning off and resetting the unit did no good. After turning the unit off for about 10 minutes it started working again. Today running 4.1, the transmitter cut off again and needed the 10 minute rest to start working again. The unit was on the window (Rainy day) and was not even warm to the touch.

I also have the dreaded .2 mile voice lag and studdering since updating to 4.0.

Other peaves...
-Whenever I update the software, it deletes all my MSN stocks and replaces them with Garmin stock
-Why do I start getting battery alerts when it hit 50% and then it beeps at me every minute for the next hour. Even after I press the OK button dozens of times. Very irritating when using it to listen to MP3's.

The only thing a Class Action Lawsuit will accomplish is to make some lawyers richer.

Class Action Lawsuits were designed to only help lawyers. If anything does trickle down to the actual plaintiffs it is referred to as side effects, such as you may have while taking certain medicines. Meaning you may or may not receive anything, but the lawyers will.

About 20 years ago I was included in a class action lawsuit against American Express for some billing irregularities. When the lawsuit was finalized I received $0.58. The lawyers (6 of them) divided up over 200 million.

Anyway it probably would not work anyway. READ THE DISCLAIMER you agree to prior to UPDATING.

Excerpt from the Agreement:
"The software is provided on an "as is" basis without warranty of any kind — either expressed or implied — including, without limitation, any implied warranties of merchantability or fitness for a particular purpose. Garmin does not warrant the performance of the software or that the software will meet your requirements or operate error free."

Works great - I noticed that some are reporting a slight delay. (Just me thinking) I believe that it is all dependent on how the map is overlaid onto the coordinate vector grid in a specific area. If it is off on the placement, the appearance of the icon tracking ahead or behind a location is plausible. This is the same as google maps when you see the drawn street not lining up with the photo only in the GPSr it is the graphics overlaid onto the coordinate vector grid.

So far it works great! Having developed firmware for 18 years, I believe that the SW team at Garmin worked hard to get this tested and released in a short period of time. Hopefully this experience will get documented in their lessons learned.

Downloaded on my 750. Everything OK so far. Going on a trip today. Will report back later.

I went ahead and tried the 4.1 update as I had unfortunately already updated to version 4.0. I have not tried the FM transmitter yet as I don’t usually use it as it is almost useless but I did notice one change. I have lost my Bluetooth connectivity. It was working fine before the update and now it won’t find any devices. Anyone else have this problem. Guess it is time to start looking at a Tom Tom.

Hotfix is likely just Garmin marketing-speak for SiRF InstantFix II. That has been present on the 700 series since release 2.6.

To refresh everyone, I ran two 760's side by side with v4.0. Both performed nearly identically on my 45min commute to work with 11 turns in the countryside and 6 turns in the city. Nearly all of the first alerts for the countryside driving were at least 0.1 mile late. About half the second alerts for the turns were .2 miles late. The rest were .1 late. ALL of the final announcements were either right at the turn or happened just after the turn. This was influenced by whether there was a stop or not. All of the final turn announcements for the city turns were either right at, or just after, the turn.
I then updated one of the 760's to v 4.1 and repeated the drive comparing v4.0 to v4.1 side by side on the same rout. On my drive to work this morning, I saw NO difference in the performance between the unit using v4.0 and the one using v4.1. One exception is with 2 of the turns, the v4.1 gave the alert at a point .1 sooner than the v4.0. It was still .1 late, namely it alerted .8 miles at .7 miles and the v4.0 alerted .7 at .6 miles. Also, of the 44 turn alerts I was able to record timing for (out of about 50+), 8 alerts happened at EXACTLY the same time and sounded kind of neat. Sort of like the stereoplex button on old tuner/amplifiers. The rest were slightly offset from each other with one or the other being a few momment or so ahead. I would deem these two versions to be identical on the tardiness of the instructions. I'll do a hard reset again on the unit sent to me on RMA that is now at v4.1, repeat the test on the way home, and then return it to Garmin. I guess I'll stick to my earlier assessment that the delayed instructions won't be fixed until the next version at best, but most likely the one after that if we're lucky.
Keep in mind that I also have a 750v3.1 that performs admirably with respect to alert timeliness on this same route using all the same map data (2009).
By the way, if the unit is in 2D mode with TTS voice, or if a non-TTS voice is used in 3D, the delay is very much reduced to the point of being acceptable. Perhaps those that don't carp about the delay are running in 2D mode.

edit: corrected some grammer

Here's a suggestion for Garmin to implement in their next firmware release that doesn't address the main issues that are frustrating us:
They should change the voice directions to say...
"Hey you just missed your turn .2 miles ago, turn around and try again."

That's funny. But it has already happened to me.
Jill: "Turn left on 4th Ave. - Recalculating - Make a U-Turn."
This really happened.

I know that a some of 7xx owners are complaining about the turn announcement delay, and some say they are not having trouble.

I was just wondering if those that do have the trouble have made changes to the TTS voice files.

If you have, try testing by maybe putting the original TTS file back into the 7xx. and see if this might make a difference.

I don't know if the modified TTS files does make a difference but just an observation. Sometimes small changes in file sums can cause problems.

Just a thought.

I am running 2.9 on my 750 so I am not experiencing any problem. I had updated to 4.0 but then reverted back to 2.9 so I could keep my LOG TRACKING availability from ver 2.3

Out of curiosity, have you tried using "British-English Daniel" as your TTS voice? I don't think I've heard of any UK users complaining about the delayed announcements and wonder if that could be the difference? (The TTS voices seem to contain the whole speech engine and so could, I suppose differ by quite a bit...)

It would be interesting to know if this has any bearing on the problem, though I realise it may not be an acceptable solution.

I have only been using stock Jill or non-TTS American English so far and I have not modified any of the voices.
After my test drive home tonight, I'll switch to Daniel or Karen (I like her better) and try a comaprison between the two units again. As an engineer, given enough time and a sufficient supply of GPS units, I could probably determine exactly what the problem is. Unfortunately, that should not be my purview.

Maybe this explains why some people with the 760's are seeing a far different degree of problem then others. Mine has the SiRFstarIII chipset and my problems have been very minor with just the slight announcement delay.

Saw this just posted today on another website by the GpsPasSion site moderator himself:

"Well it seems I got lucky, I was still running v3.10 and noticed the hidden log feature was gone, so I downgraded to v2.3, lost all my settings in the process and then let the webupdater update my 760 to v4.10. So far so good, I was paying particular attention to any type of delays and I'm not seeing any, if anything the display seems more "fluid" than in v3.01, not at the level of the 255's 4Hz of course, but delay in getting the map rotated after a turn seems lower.

Also is it me or have they done something to the display, it seems "smoother" for some reason, maybe it's because I switched back to the 760 after using the 860 for a couple of months.

It's going to be hard for Garmin to troubleshoot if some are having problems and others not. They were probably asking for trouble by using different hardware bits though. My 760 is one of the earlier models with the SiRFstarIII chipset and the bright screen, not the later ones with MTK and poorer screen described in this topic ( http://www.gpspassion.com/FORUMSEN/topic.asp?TOPIC_ID=113883 ). I think the easiest way to check is to look at the SW version of the GPS module, v3.00 is SiRFstarIII and v2.60 is MTK."

I just tried your suggestion and noticed that the turn announcement voice lag is narly now completely gone. The "British-English Daniel" is a version 1.10 voice while the American versions I was using were Jill version 1.90 and Jack 1.40 that I had updated. You may have found at least a temporary solution to a lot of people's problems.

Are previous versions of Jill available anyplace? I looked on Perry's site that has the previous SW versions and didn't see any voice files but was curious...

Jill V1.80 is here:
http://www8.garmin.com/software/Voice,AmericanEnglish-Jill_T...

Jack V1.30:

Did you have to travel "up the hill" to find these Hornbyp?

Thanks! Looks like another permutation to work through...

Is it enabled? If so, try rloading the firmware from the status/maintenance screen by pressing and holding the speedometer. Once in, keep pressing next until you are in the Bluetooth status screen. You should see if bluetooth is enabled, etc. Press the "Updt PR" button to update the bluetooth version that was last flashed to the device. Wait for it to finish loading and try to reconnect to your devices.

Just got my 760 a couple of weeks ago. I played with it for two days, add favorites, customized other settings. Seemed to be working fine. Then I went to garmin's site, registered the unit, and updated both the software and the maps to what was then the latest on their website (3.10 and 2009 north amer map). Then the problems started. Whenever I would navigate with the fm traffic cable attached, the map display would be slow to update, and then freeze. (just the map was frozen, not the text or voice directions). I would have to reset the unit to get the map working again. Got sidetracked by the fact that this symptom only happened with the traffic receiver attached, worked fine on battery power.

Not knowing what else to do, and Garmin tech support telling me to return my traffic cable, I decided to try resetting the user data (power on with finger press in lower right corner) to factory defaults. The damn thing has worked fine ever since (of course, it has only been two days, so I'm still holding my breath).

My point and/or question being: Is it possible that upgrading the software and/or maps may leave the unit in some quasi running state and user data reset fixes it?

If so, that could be pretty nasty for anyone who has made extensive favorite additions.
