Nuvi 7x0 firmware 5.1

Can you share with us the bypass routine so we can also skip firmware updates at map update times

Sure. If someone wants to add it to the FAQ page, feel free. This was written a few years ago by myself but it should still work just as well.

I've been using this method for + 2 years and it works as described.

I suspect there will be a 7x5 update coming. I have a 755T refurb from Garmin that came with 4.10 and there is a 4.10 update.GCD already flaoting around the web.

Just plugged my 765T in and ran Webupdater. No 4.10 offered yet (nor any other update for that matter).

Following is Garmin's response to my email query regarding the aborted 5.1 firmware.

"Dear ______,

Thank you for contacting Garmin International. I will be happy to help you with this. When the engineers get all the problems corrected with the software, they will schedule a release of the software again. The software may not be named 5.1 though as they had released that and pulled it back. If you have any other questions, please reply to this email. Thank you."

Sounds a little opened ended to me......

Thanks Dorkusnimrod

I am having the same issue with my nuvi760, the "master reset" will only work for about 2 weeks at a time and them my unit locks up during the boot process when connected to the car dock or shuts off after about 10 seconds when not attached...Garmin insists that this is a hardware issue and wants $108.65 for a refurbished unit...As I have tried to explain to several of their "Product Support Specialists" the unit worked fine prior to the 5.1 update...

Darn, that's too bad. I can report that my 750 with 5.1 is still working, BUT this is a backup GPS for me so it's rarely used and if used more frequently, maybe I'd have your 5.1 760 issues, too.

Can you go back to the "now current" firmware 4.90 and see if that reverts your brick to a functional GPS again?

That sounds like a bigger bug than just an install problem. But I'm still hoping there will be a 5.2. You can get 4.90 from here http://www.gawisp.com/perry/nuvi/ (Garmin support doesn't seem to be listing anything for the 750/760 at the moment) and try the reinstall like Craig suggested.

here goes trying to update. Been holding off since seeing this thread buts its nice to know that there is help here if needed

Just got off the phone with garmin...
the tech admitted there was a problem with 5.1 and it had been pulled from the website, he claims to be sending me the 4.9 file and instructions to install...
We'll see what happens... also, in the "x:\Garmin\GPX" folder there is a gpx file... this file contains your favorites, save it for restore later...

Since the garmin guy never sent me the file, i downloaded it from the above link and installed no problem...
Now, wait 2 weeks and see if it still works...
Maybe they will release 5.1b???

Happy at 4.8 No issues! Probably stay with this upgrade to the end of the units life.

Agreed!

this happened to my nuvi 750 when I saved 2 addresses and did not enter names. the gps froze after several seconds. sequence of events:
1. I hit "where to" button.
2. I entered address.
3. gps gave me 2 addresses, one is avenue , other one is street.
4. I hit save on first address, I did not enter a name.
5. I hit the back button.
6. I hit save on second address, I did not enter a name.
7. I hit "where to" button. I hit "recently found", I chose first address.
8. gps calculated the route, then froze after a few seconds.
9. I restarted the gps , same thing, calculated the route then froze after several seconds.
I solved the issue by doing a hard reset. this erased the "recently found" and "favorites" info.
nuvi 750 works fine now.

Well done. I've had to do a hard reset at least once to recover a nuvi after a firmware update. It's not common but does occur on occasion. I think some folks routinely do a hard reset after each firmware update just to be safe.

Note that you can save you favorites to a computer and put them back on the nuvi after a reset.

Changes made from version 4.90 to 5.30:
Important: This software update will restore user settings to default.
Fixed an error that sometimes caused units to shut down after upgrading software.

.......just not useful ones. http://www8.garmin.com/support/download_details.jsp?id=4357 The latest is version 4.4, which still hasn't fixed any of the firmware issues I successfully reported.

Just downloaded the map update 2012.4 and got 5.3 firmware forced on me -- besides for the default reset, it seems to be working fine on my 760.

Hope the 5.3 firmware works for others to!

There's already a thread about the 7x0 v5.30 firmware:
http://www.poi-factory.com/node/35861
I've been running it for a while, no problems so far.

I am never going to upgrade to 5.x. I will just keep using the Dorkusnimrod method ...now fooling the unit to believe it is at 5.3.

I had the same problem of shut off automatically on battery and hang up with external power on. So I did factory reset. Turn off your set - Press and hold bottom right corner and turn on while keep holding (Corner may vary as per model, you can try other corners) The unit will ask you to erase all data. Say yes and your problem is solved.

Thanks for the guidance

After reading this thread, I think I'll stick with 4.8 for a while too.

I understand doing a reset will erase favorites and my extra pois. But will it erase the map updates as well? What else will be gone or reset?

You may have to reset some settings like keyboard choice, tracking (3d vs up vs true north)

Just got life time maps added to the Nuvi, This is the first update since NEW in 2008. and i have to say the latest update sucks. Unit keeps shuting off and restarting, Had to down grade to 4.90. So far thats working for now. DO NOT UPDATE TO THE LATEST FIRMWARE.

Note that the current firmware is 5.30, not 5.10.

I'm running v5.1 on a 760. One of the new features I thought added with that version was to be able to enter a zip code in addition to a city name when searching for a destination. My father's 750 didn't have that with v4.9, and it still doesn't have that with v5.3.

Can someone still running with v5.1 confirm that zip code entry is present in that version? Can then someone with a 760 running v5.3 tell me if it's still in that version? It's a really nice feature, and I'd defer upgrading to v5.3 if it means it'll go away.

Thanks.

Jeff, just a quick reply here--to let you know that you may not get a reply.

From what I see in this thread, 5.1 was offered by Garmin for a period of about one day before Garmin pulled it. Of the folks who updated to 5.1, most reverted back to an earlier version.

Here at The Factory, you and I may be the only people who updated to 5.1 and got it to work and kept it. But I recently updated to the new 5.3.

It's quite possible that there's no one with 5.1 on a nuvi 7x0 that still exists who will be able to run the test you want done.

However, what might be the answer you want, my nuvi 750 with firmware 5.30 does allow searches by either City Name or ZIP code.

Therefore, I don't understand why your father's 750 doesn't offer this. If you tap WhereTo, then Address, doesn't your father see what I see:

Spell City/Postal Code
Search All
Change State/Country

I'll doublecheck my father's unit, maybe I missed seeing it.

I'm really more concerned with any 760 users w/ 5.3 - does it still have Spell City/Postal Code? I'd rather not upgrade until I know it's definitely still there.

I thought that was really a nice addition in 5.1, and I wouldn't want to lose it.

And and for v5.1, I had to do the hard reset about 4 times since I did the upgrade (one time while I was using it to navigate to a new destination - that was annoying). But other than that, I was happy with it.

Jeff

I just did the map update and it automagically updated my firmware from 4.8 to 5.30

I'm hoping it didn't screw anything up. I've stuck with 4.8 for a long time as it worked flawlessly.

What exactly is a cold reset?
Is that pressing a corner of the screen while powering up the 750 ?

Also what do you use to save the Favorites?

Ugh, both 5.10 and 5.30 have been pulled by Garmin:

http://www.poi-factory.com/node/36437

I haven't updated my 760 since the fix for the firmware 4.0 fiasco. I have found it's hit or miss with Garmin's firmware updates.

Garmin pulled the 5.30 firmware. I'm happy they did as it caused my GPS to keep turning off. I edited my GarminDevice.xml and changed the version to some random number that was older then connected to the updater. It asked if I wanted to install 4.90 and I took it. I'm back to a stable version. I'll be more careful next time there's a map update.

I installed the 5.30 update previously and my Garmin froze up on me on several occasions while driving in Okinawa.

The reset helps to fix the system for a while, but the issue comes back.

I thought it had been resolved as I left the unit running while attached to my laptop, but the other day I was following a route in the mountains near Tokyo and it crapped out again.

Very disappointing.

I couldnt find a clear link or information how to rollback the software to 4.9. Any help is appreciated.

There may be two ways to revert to 4.90:

First, there's a link to the firmware update file at the perry site--scroll down to find and save the nuvi750_490.exe file to your computer:

http://gawisp.com/perry/nuvi/

You may want someone to confirm the method for doing this. I think it may be simply connection your 750 to the computer, then running the exe program. But then, maybe running the program just creates files on your PC that need to be copied over to your 750. Or....?

Second, you can use the method described by thrak just above your post by editing the GarminDevice.xml file to fool WebUpdater into thinking you have firmware ealier than 4.9 and allow WebUpdater to install 4.90. I used thrak's method and simply used Window's Notepad to edit the file. Look for SoftwareVersion within a < and >, then change the 530 that follows to something like 480, then save the file. I did find that since GarminDevice.xml is an output file created by the nuvi, it's necessary to edit the xml file and run WebUpdater during the same power cycle; i.e., don't let the 750 turn off after editing the xml file and before running WebUpdater since your edited file will be overwritten with 530 again during your nuvi's boot.

As always, use one of these methods to backdate your firmware at your own risk, especially since I approached my risk tolerance limit when I did this for my 750 and may not know all the risks or limitations to what I've just suggested!

Good luck and report back.

Thanks for the advice. I had modified the XML file previously, but didnt consider the power cycle. Did again and its "updating" to 4.90 now.

Also, just FYI or anyone, read that one of the "perks" of 5.30 was that it would allow a 2nd mapset on the SD using gmapsup1. I tried it and it does work, so it would be nice if they got everything sorted out for those who wish to use multiple mapsets.

Or you can just use GMAPtool...

Good work--and a big thanks to DorkusNimrod and thrak, too.

Thank you very much. My Garmin has been doing this power off thing for 3 months now. I did the cold shut down as directed in the link. Though I lost my stored address and other user data, the issue was gone just like that. It is now more than 20 minutes, and the unit is still on
