Can't Backdate Firmware After Updating To 4.00

 

I updated my nuvi 760 to 4.00.
I was having some problems, so I wanted to backdate to 2.90, just to see if it was a problem with 4.00.

I ran the nuvi760_290.exe file, and it seemed to download to the device ok, but when I dissconnected from my computer and power up the nuvi it doesn't update the firmware.

I've made several attemps, but 4.00 remains.

Any help?

I had problems w/ 4.00 and

I had problems w/ 4.00 and late directions on turns today after updating my 760 yesterday, so I also tried to revert back but to 3.10.

Just like you, after restarting 4.00 remains. Hopefully, someone will be able to provide some insight.

Same on a 750

I've had a lot of problems with this new update. Thankfully this GPS is less than a week old so back it goes. Note to self...no more updates unless I NEED it.

Just downloaded and

Just downloaded and installed the update in my 750. Hope it works OK.

Try this

At your own risk of course...

When you hook your unit to the computer, go to the drive letter the system creates for it - and navigate to the Garmin folder - and make a copy of the file GUPDATE.GCD on your computer, and delete it on the folder for your unit - then run the install folder for the older firmware version. It should put the older version's file on the Nuvi, and it should see it as a 'new' update, and load that when you reboot the Nuvi.

Maybe I can copy it in from my backup and try again.

I'll let you all know what happens........

Well I took a look a the

Well I took a look a the diagnostic screen, 2nd page/ start test/more.

If I scroll down it now shows....

PROM 2 Erased
Dir DB Erased
Demo Erased
GTM20 Erased
SIRF Erased

Anybody else have the same?

Update.... My bad. I moved the Remote SW folder by mistake.

Now I have GTM20 and SIRF back

When booting.....

Anybody else notice while booting up, at the bottom of the screen, it now says....

I thought it used to just say.....

Go To This Page...

Go to this page look for your GPS and it has all the previous updates. Let us know how it goes...

Report the Lag issue, and any others noticed

Go to http://www.garmin.com/garmin/cms/site/us/lang/en/supportcont... and click the link under "Email Product Support" and let them know about the lag if you experience it - and any other issues too.

Report the Lag issue

I reported it using the above link. The .1 mile lag is the only thing I noticed. When I get near the turn it seems to catch up. Everything else seems to be working better than before under 3.10.

This is insane

Yes, there is a lag. Yes, it has told me to turn AFTER I had already done so. No, I can't revert to 3.0.

I am to the point of trying to completely erasing the thing and copying a backup onto it. I am just afraid it won't work afterward.

Previous Updates

When you follow the link you provided, it takes you to a list, but when you click on your model, it downloads the quick start menu. Perhaps you’ve provided the wrong link?

It Works...

Just find your Model GPS and the update you want to install. Save it to your desktop and the run it. It will guide you to the installation of that particular update. I have used it and it works.

Also...

If your update is not on the list of the link I provided just go to PARENT DIRECTORY and navigate to your GPS model.

Are you referring to my comment?

If so, you are mistaken. After installing the 4.0 update, you can't go back. I am wondering if deleting and then copying the backup to the unit would work?

Never mind. I re-read your post and figured it out. Sorry.

Restoring with backup files will not work with firmware

That will not work because the firmware is not part of your backup. The firmware is flashed to a different EProm memory chip like a computer uses for it's bios that you cannot access and was never backed up.

That's a bummer you can't even use your original files to do a restore.Wonder what garmin's reasoning is with this update?

Probably it wasn't intentional but rather just a glitch in the programming.

I don’t believe it’s unintentional...

I may be incorrect, but I believe it's part of an effort to stop hackers... The new version of MapSource took away the ability to add unlock codes manually, you now have to go through Garmin to unlock maps. This is no big deal if you purchase your maps from Garmin or a Garmin dealer, but if you use pirated maps it will stop you. It's part of Garmin’s effort to protect their software/maps from pirating, and we are caught up in their effort.

Sloppy

It seems to me that Garmin is getting a little sloppy when it comes to testing updates properly before their release. Trying to stay one step ahead of the competion is leading to a few stumbles.

It's very simple to prove just connect your GPS to the computer and access the files on the drive. Now just select all files and directories and erase them so everything is gone and it is completely wiped clean. Now take your complete older backup file set you saved from before and copy it back on to the unit. If the firmware was part of the old backup set when the unit now starts up it should have the old firmware that was in the unit when you did the complete backup but what you will find is you will still have the latest firmware that you installed last but just older data files such as routes, vehicles, favorites, etc. Firmware is installed in flash Eprom memory and the rest of the data files are installed in RAM (random access memory)memory.

If the firmware update was just part of the rest of the files then the process that the GPS goes through when you first start it after doing the update would not be needed. You will notice after you do a firmware update that the GPS goes through an install process where it is actually erasing the existing firmware on the eprom chip and then replaces it with the new firmware from the file it downloaded during the upgrade. If it just needed to copy it into the drive their would be no install process needed.

Not quite. Everything is kept in flash, but the flash is divided into different areas - the actual firmware which gets loaded is stored in a different area than that made available as a USB drive.

Basically, when an update is done, a file (gupdate.gcd) is copied to the user accessable USB drive area of the flash. When the unit boots, it sees that firmware file, recognizes it as different than the running version and copies it to the firmware area of the flash. With 4.0, it's probably only looking for a newer version, which is why you can't downgrade.

The actual process is likely a bit more complex, I suspect gupdate.gcd is really a container for multiple files, which end up getting distributed to different locations, as appropriate.

RAM is used for temporary storage when the unit is running.

Once again.....

OK, both you guys are making a logical sounding case but logic, no matter how good, sometimes leads you to incorrect conclusions.

There appears to be some BIG assumptions in both your messages.

So.....the question remains: How do you KNOW that?

If Garmin doesn't use a "standard" base operating system, then there could be LOTS of other ways things could be done......like a protected area of SRAM that you simply can't see or get to.

Nuvi 360 and BT v3.10

The only limitations I have found on the 360 is the BT firmware. I installed v3.10 and had problems. I tried to go back to v2.90 (last known good) and even though the system told me it was v2.90, I had the same problems v3.10 caused. There is some file, somewhere that was not changed and is integral to the function of BT. I emailed Garmin and they could not find a solution either.

That's not what I meant and you know it.

So I guess that means that you really don't know what memory is inside and how it is used.

No, it's just I know when someone is trolling for a pissing match. The information is available to those with the ability to find it. I take it you've never even opened a Nuvi or explored the diagnostic screens.

garmin problem

So does anyone know if Garmin admits there is a problem? Or should we all be contacting Garmin to complain.

Saw this posted in another thread:

"Garmin is working on a fix.........
Here is a message I received from Garmin Support after I sent some screen shots of the problems with 4.00..........

Phil, your right. That is definitely not right. I talked to my supervisor and a software support specialist. They both said there is a BUG with the 700 series right now, when you update it. They said there is a firmware update suppose to be coming out. The way they talked it should be within the week. I will check and let you know as soon as it happens. Unfortunately we can't backdate anything with these units. Sorry about this, and I appreciate your patience. I'll let you know something either later today, or the first of next week. Thanks Phil. Have a great weekend.

Thank you for contacting Garmin Product Support.

4.00

Does this problem effect the 650? I just did a update to 4.00 the other day but I have not used it since.
And what problems do you see?

I haven't seen any problems with my 760

Others have said that the notification of up coming turns is later than previously.... The other discussed subject for the 7xx series is not being able to revert to a previous version....

I've been going back & forth with support by email today

The last thing they told me was to "update the voice files"...

To which I replied, " WebUpdater does not give me any updates for voices in a language I'm likely to ever use"...

Still waiting for a reply to that one. smile

This is the reply I received from garmin support. I complained about not being able to revert back to another version, and about the voice lag.

Thank you for contacting Garmin International.
Try to do a master reset.

To do a master reset on your unit, please take the unit outdoors and
with the unit turned off press and hold down the bottom right corner of
the screen, if possible with the back of a pencil eraser, then press the
power button until the screen comes on, and then let go of the power
button. Keep holding down the eraser on the screen until the Erase all
User Data appears. Hit yes and the unit will be reset.
Caution, this will erase all user data including waypoints (will not
affect maps). Please stay on the Where to and view map screen, Keep an
eye on the satellite bars in the upper right corner of the screen, the
bars should turn red and then green for a full satellite signal.

To back your favorites, connect the unit to the computer.

Double click my Computer Icon
Click on the Garmin Drive
Click on the Garmin Folder
Click on the GPX Folder

I got the same email

Only this guy suggested one other thing:

"Also keep in mind it also tells you where to turn on the unit itself, so you can also follow the map that way."

So, in other words, just keep your eye on the unit while you drive so that you can see the turns in time.

I guess I wasted my money paying for the text to speech, since I now just need to watch the unit while driving, If this is the case I may get back a rebate.

Files cannot be firmware

Um, if it's called FIRMWARE, it is not a file stored in memory. There's a reason it's called FIRMware. Firmware is not accessed through the file system like SOFTware.
