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?

I wonder if the stuttering is only a problem for a certain chipset. Mine is only a month old with a different chip and screen from the ones sold in early 2008.

Problems

I have read about these problems and the voice issue is null for me as I don't turn on the voice part. The scrolling issue I don't have a problem as far as I can tell. But if exact examples were given with settings then one might be able to determine exactly what was going on. I wouldn't mine knowing more of what your scrolling at what time. Just trying to learn more about this unit.

Haven't had a stutter

Which voice are you using? Have you tried different voices? Have you updated the voices as well?

Still experiencing stuttering?

If you had updated the latest version of the voices, and still experiencing the stuttering one suggestion would be to try my voice file.

Since I don't have any stuttering issue, I can e-mail the voice file I am using (Modified version of Karen TTS) and you can use it to see if that fixes the problem for you.

My customizations aren't too bad, at least not to me! (OK-instead of recalculating, ENGAGE-instead of 'Drive to highlighted route' and a few other small things), but the idea is just to trouble-shoot and find a work around.

If interested post here or e-mail me via my contact info.

I have stuttering problems & Scrolling issues w/ custom Pois.

The problems are on my Nuvi 770. When I had ver 4.2, I didnt have the problems, but now that I have 4.6, they are back. The Stuttering is with Karen TTS and also Elfred and Dr. Nightmare.

When it stutters, is the map

When it stutters, is the map display in 2D or 3D
mode ... I've got a hunch it is related to 2D mode.

NUVI 200W Issues

My friend just registered her new 200W and it did the auto update. Afterward her unit was locked. However, after some time on the phone with Garmin Support they updated her unit with a new file and it's working great now.

Wierd that the updater version is a problem and the direct worked fine.

Also, Garmin told her the problem had something to do with a "slow" USB cable???

That is directly related with the load on the computer: It is not able to handle the speech generation and the map recalculation -- both of which are pretty computer intensives -- at the same time. The priority is given to the TTS as any delay there would result in stuttering (the very problem some people have reported).

Does the new update have any

Does the new update have any improvement in startup time? My 760 seems to take a very long time to start up using the v4.2 firmware. I've read that this is due to some sort of defragging.

The stuttering happens in 2D as I dont use 3D

The way I view it, is that it's an issue for me in 2D mode. You may be correct in your hunch, but it's still a problem that needs attention no matter what mode is being used.... Bugs iz bugs.

Those who are having the scrolling problem - does it happen with Custom POI files that just have single line entires or does happen just with Custom POI files that have multiple line entires?

I have some POI files that I have downloaded from this site that are just made up of single line entires like this:

-94.74240,38.81952,Heritage Park,Perfect site for a picnic

and they seem to scroll correctly.

However, I have some that I have downloaded - and some that I have created myself - that have multiline entries for each location like this:

-94.76416,38.81227,Garmin,"1200 E. 151st Street
Olathe,KS 66062
913/397.8300"

that all have the scrolling problem.

For those who have the other problems but say you don't have the scrolling problem - have you tried this on any multi-line files?

I have both on my 760 and do not have the scrolling issue with either of them.

I also do not have the stuttering issue.

It could be any number of variables in the mix causing the intermittent occurences.

My 760 takes longer to boot now.

The maps are also slow to respond. When it's done calculating, the map does not move for 5 seconds. Aside from that, no stuttering at all.

No stuttering in any mode

I tried all three display modes. No stuttering at all, using the Jill TTS voice.

Thanks for the update!

Thanks, I'll keep to the 4.2 version, as I don't seem to have any problems with it... except for the really long time it seems to take to load my mp3 files, but then I have 7gb of songs laugh out loud

Think I will stay with 4.2 for a bit

Here's hoping they release a fix for the stuttering and other issues soon.

Once burned..........

After being burned badly in the previous firmware debacle going from 3x to 4x I'm going to hold off a while on this one. The last time I jumped on the bandwagon as an early adopter my 760 developed a horrid lag when announcing turns and caused me a lot of grief in high-traffic, quick-decision, environments because it waited far too long to let me know I needed to turn.

Stuttering with 2D after the upgrade to 4.6 on Nuvi 760

My 760 stutters after the upgrade to 4.6. I tried different voices in vain, called Garmin and was given a permission to send in my unit for a replacement. Their theory: the speaker connection on the unit might be bad. Since I'm not totally convinced about their theory, I'll try 3D first Before sending mine in for a replacement. BTW, I switched to 2D during the 4.0 fiasco and was able to get around the stuttering problem. Now, I'll really be very careful before upgrading to a new firmware.

From the Garmin website:

Changes made from version 4.20 to 4.60:
Correction to optimal route reordering.
Added support for two traffic providers.
Corrected issue with speed limits on certain roads.

4.6

It fixes the routing issues when you try to make a route with more than 6 via points. Under 4.2 it would drop a random via point and duplicate the last one when you tried to optimize the route. 4.6 has fixed that.

Since I don't use the routing features that often or with that many way points.... think I'll wait this one out.

Thanks to everyone for sharing their comments on it.

Firmware 4.6 changes

Thanks, Bstpm. I went to the Garmin site after reading your post and realized I would have to drill down three pages in the download area to find the list of version changes.

It was interesting to note that, according to Garmin, the upgrade from 4.10 to 4.20 "fixed" the stuttering issue.

I wonder what happened to missing upgrades 4.30, 4.40 and 4.50.

4.5 was for a Seller Specific unit. Cosco, I think. Perhaps 4.3 and 4.4 were also.

750 with stuttering and map set to 2D

My 750 has regained the stuttering feature after going to 4.60 - and my map is set to 2D (I hate the 3D view). The stuttering is extremely bad, most times breaking it up syllable by syllable. I have gone back to 4.20 - runing the 4.20 update exe file will put the 4.20 file on the nuvi and the next time it is powered on it asks if you want to load the older software, it works - I verified mine has gone back to 4.20.

I am going to leave mine at 4.20 until it doesn't work any more - such as when my GPS V needed an update after , oh it must have been 4 or 5 years at least, when they updated the WASS satelites.

BTW GPS V is now at 2.60 - if you have one that the screen goes blank after a minute and the unit locks up, this may fix your problem.

I am going to go back to my trusty old Street Pilot 2610 for work until things with the nuvi's settle out.

Stuttering

Noticed the last few days that the stuttering was back but only when I am viewing traffic by road. As soon as I hit back to go to the traffic map the stuttering stops right away.

Garmin SP 2730 and Nuvi 760

I have a Nuvi 710 that just

I have a Nuvi 710 that just upgraded to 4.6 and have voice stuttering and map update issues.

What I have notived however is that it doesn't seem related to voice use. I drove for a while with the unit switched on and displaying my current location, i.e. not navigating, and still the map update pauses every so often. Further tests show that when I looked at the world clock function the unit would skip odd seconds every now and then, and on occasion 10 - 15 seconds. So I'm inclined to think it has nothing to do with the voice files, but some other bug that is hogging the processor every so often.

Re: Frozen map during speech

I used to own a Garmin Nuvi 260W were this did not occur. The map never froze while the voice spoke and the voice never had stuttering issues either. I thought the 760 was supposed to be better than the 260W. Is there something different about the processor in the 260W or is it the voices it uses are less processor-intensive? Could anyone answer this?

So you're saying that at one time your 760 didn't have the lag while announcing turns? What firmware did you have at that time? and What firmware do you have now?

Defragging ?

Seems to be an interesting theory. All computers suffer from slow file access due to file fragmentation. But im not sure with the fast access speeds of flash memory (internal as well as the sd card) that file fragmentation would cause a 760 to start up slow (something I've also seen in my own 760). Some people have suggested (although not practical) to turn the unit on for 20 minutes with a clear view of the sky and the long start up will be cut down to about 5 to 10 seconds. I'll try defragging the files on my 760's internal and sd card flash memories to see if the start up time improves. I'll let you know how it goes.

Hardware Revisions ?

So is there more than one hardware revision for the Nuvi 760? Which ones are there and how do I check my Nuvi 760's hardware revision?

.

The defrag process being referred to is the nuvi's own internal defrag routine which -seems- to be triggered when doing any route manipulation on the unit. At the time of the defrag, the "Loading maps" message will stay on the screen for sometimes minutes at a time. When this happens, it's best to simply wait out the message since interrupting it seems to make things worse. It's also unknown if the unit is defragging it's internal storage area or a RAM defrag.

I doubt that anything you do as far as defragging the nuvi drive will help since it's an automatic process.

I'm still curious though as to what would happen if I defragged the files on the units internal and sd card flashes. A Couple of times I interrupted the long start up (loading maps message) on the 760 since the Wife's impatient nature/comments was urging me to get us on our way to our destination and what happened was that some of the 760's settings were changed. Most notibly the voice setting was changed to not use any voice at all (??).

if the defag is interrupted the voice setting goes away

You are correct that if the defag is interrupted the voice setting goes away. It happened to my 760 when I did that and I quickly learned to just let it finish completely and there are no problems.

I used to just automatically update the firmware whenever a new version was available. When I had the 3x firmware my 760 was rock solid. When I went to the first 4x firmware it was horrible. 4.2 pretty much fixed it and now I'm gun shy as far as jumping on the firmware update bandwagon.

YES

It happens during route calculation for me. If I miss a turn or if there's another immediate turn.

Well, after a week, I don't *seem* to have any issues on mine with the upgrade, but I neaver really ran it without, so I'm not sure. I have not yet done anything with custom POIs...

I do find it interesting that sometimes it take forever to boot (like when I'm in a hurry). Nice to know about the defrag thing.

I defragged to files on both the internal (took a very long time) and sd card flash rams. There was no noticeable improvement in the Nuvi 760's boot-up time. What I've noticed that does have an obvious improvement on the boot-up time is turning the unit on and leaving it alone where it can get a good signal from satellites for about 10 to 20 minutes. For the next 6 hours, maybe the rest of the day, the 760 will boot-up in about 3 to 6 seconds even after turning it off.

.

What triggers the defrag to occur in -most- instances is the creation/modification/saving of routes done on the GPS unit itself. After the next power cycle, a defrag instance is very likely to occur. Interrupting the defrag will cause other problems such as the current voice settings to be lost/reset to something else.

Route scrolling issue with Custom POIs in 4.2

I was able to reproduce the custom POIs near my route issue in 4.6, and I know that it had been fixed in 4.2, so the bug has been resurrected.

Now the strange thing is it does it to me on 4.2 I downgraded back to 4.2 after the stuttering problem in 4.6 got to be pretty bad. I didn't test this issue out when I was in on 4.2 before. So I can't confirm if this issue was carried back with me to 4.2 from 4.6

I have a 750 and I still have 4.2. I just confirmed that the scrolling issue is there when scrolling through custom POIs Near... "My Current Route". This does not occur when selecting the other "Near..." options or on built in POIs. I also noticed that I get an extremely short list of options when I use Near... "My Current Route". I'm not sure if this is a bug or if the search logic is extremely restrictive. There are also issues when selecting a specific category then using the back button and changing to All Categories. When you do this, it still only searches on the original category. The bottom line is that there seems to be some problems with "My Current Route" logic in 4.2 and I'm a little hesitant to upgrade to 4.6 because I don't want the stuttering problem. Hold on...just noticed one more thing. I have a custom POI that I created from my Current.gpx using POILoader. When I scroll through that list (using My Current Route), the 1st line doesn't change but the 2nd line does. I know someone had asked about 1 line vs. 2 line custom POIs so I hope this answers that question.
