nuvi 7x0 firmware update v4.90 released

Thanks for the heads-up.

Cool

Thx.

Ditto

So who in this neighborhood will be the first to try this update? I am waiting for a couple of positive (or at least not negative) reports...

Appreciate the heads-up...

Just downloaded the update for my nuvi 750..Garmin did put a blurb in there that if your batteries fail during the software install your unit will become unstable and will have to be returned to garmin for servicing..

I haven't updated in quite a while. I used to update EVERY time I could until the Great Debacle back around version 4 or so. My 760 was borked for too long before they issued an update that fixed it again. Since then I've been pretty leery of updating since it seems to work just fine as it is.

I also would like to know how it works on the nuvi 750. Thanks!

I just updated my 780 via Garmin's myDashboard... works fine for me.

Got mine !!

so far so good !!

After updating my nuvi 750 and using it for several days now..it actually works much better now!

Care to elaborate?

Thanks for the update info!

Will grab and install soon as long as there are not reports of problems. My existing version is working pretty well now.

The reason for the warning about the battery: When connected via USB to the PC, the update file gets copied to the nüvi. The actual update happens when it powers on after you disconnect from the PC. It takes a few minutes so if the battery died there is a potential for a hosed firmware load and the device might not boot again. It has always been this way, same is true for flashing firmware on your PC's motherboard.

If there is a concern about the battery condition, connect it to your wall or car charger before turning it on the 1st time so that it will have a constant power source when it comes up loading the new software.

Yeah. I'm gonna let someone else plow this road.

Burn me once, shame on you. Burn me twice, shame on me.

and everything seems to be fine.

I have been getting the Low battery warning all the time with my 760..and I know it is not dead..will let you know if this works..

Thanks!!

Everything working OK so far?

I've had my nuvi 750 for a long time now and been through many firmware changes without any issues (except the dreaded delayed TTS voice issue several firmware versions ago...) and not had any issue with a firware update. I've also never had any issue with my nuvi 750 freezing up.

After installing this new firmware, my nuvi 750 has frozen up about 4 times on two different days. The display freezes and the touch screen doesn't respond. Luckily, I am still able to turn off my nuvi and turn it back on again to "unstick" it.

Has anyone else found screen freezes a new issue or issue of increased incidence following this firmware update?

Any suggestions on what I may do to eliminate this issue for me?

The trojan that bricked 1000's of 7X5 units didn't appear until about a month after the update was loaded

Hard Reset warnings:

* Note that this procedure has been known to periodically delete your favorites so back them up beforehand: From the nuvi drive, copy x:/Garmin/GPX/current.gpx to your backup location. After the hard reset, copy current.gpx back to the same folder on the nuvi but rename it temp.gpx(important). On the next power cycle, the favorites will be read from temp.gpx into the non-user accessible memory area on the nuvi where they are actually stored (current.gpx is only a shadowed backup of your favorites)

* Note that this procedure will clear all user selected settings under Tools>Settings like map view mode, navigational settings, selected vehicle, selected voice, etc. These settings will need to be re-configured afterwards. Maps, vehicles, voices and user-loaded custom POI's stored on the unit will not be disturbed.

Hard Reset Procedure:

*Note that a "power-cycle" (or power-on/power off sequence) on the nuvi 8x0/8x5 units consists of removing, then reinserting the battery into the unit. Using the power switch on the unit to power it off only puts it into a "sleep" mode.

Power the unit off. Press and hold (and continue to hold) the bottom-right corner of the screen while powering the unit on. Continue to hold the screen until the "Do you want to erase all user data?" prompt appears. Press "yes" and the unit will reboot. Reset all your location settings and user preferences.

If possible after the hard reset, let the unit sit outdoors in the open for about 30 minutes or so to let the unit re-acquire the satellite almanac data.

Hi Craig

If the unit acts strangely after a firmware update, I strongly suggest you do a hard reset.

Apparently this sort of behaviour isn't that uncommon after a firmware update. Before performing the reset, don't forget to back up your favorites because theres a good chance you'll lose them.

Good luck

Thanks. In doing so, my last RTL Trap was back in January. My three most recent events (corresponding to my three freezeups) are Data Aborts: one two days ago and two today. Any thoughts on what's wrong if the errors are "Data Aborts?"

I guess I'll try the backup and hard reset route. More to follow maybe...wish me luck.

Whoops, just reread the post and found that there is a new update. I was working with 4.80. I tried the Hard Reset, but is didn't solve my problem.

Thanks for the info to spare me looking for the hard reset procedure. I've printed it out for potential future use, too.

Hard reset redone (and yes, my Favorites dropped from the mid 60s to 44 of them), so the CopyToPC/Rename/RestoreToNuvi was important for me.

So far so good--I've now reset my languages, etc. and am reacquiring satellite data. We'll see now over the next few days if this fixes the Data Abort errors that froze my screen.

Thanks again for the tip and procedure!

No complaints with the current one, but I'll go ahead and update.

Thanks...

DorkusNimrod,

Thanks for the very detailed info.

I am printing it off now to store in my GPS Library.

Regards

Most of the updates I just installed without hesitation, and I never had any of the big problems that others ran across. But since it's working so well these days I'll wait until CraigW has had time to see if the reset fixed his problem.

The hard reset (with saving and recovery of Favorites and resetting of non-default items) seems to be working. After the hard reset last night, I tried it in town on 3-4 trips today and had no freezeups. So (fingers crossed) my three freezing issues after the last firmware update were not firmware issues since they were resolved with the hard reset.

No. There was no "trojan." Just buggy software.

The TOPO maps on my SD card will not work after the update. Can someone help me fix this?
Thx,
Jen

Were the Topo maps purchased from Garmin or did you get them from a 3rd party download?

Jen, I updated to the new 4.90 firmware and still can use a free Arizona Topo map on an SD card as well as using Garmin's Topo US 2008 on SD with my nuvi. The Garmin Topo US 2008 map was from the Topo DVD and using Mapsource to load about 1/3 of the USA--since the entire Topo US 2008 has too many segments to be readable by a nuvi.

When you try to use your topo map on an SD card, do you deselect the City Navigator map so that only the topo map is active? If not, City Navigator won't let the topo be seen even though both are selected. When you go to your Map Info page, are both the City Navigator and topo identified?

If this isn't the issue, let us know which nuvi you have, which firmware, which City Navigator and which topo map--and was the topo map purchased directly from Garmin on SD or did you create your own map with Mapsource for the SD?

Wednesday I took my 760 in a friend's car and it unexpectedly died. It would not turn on again and no power from a working USB port on my PC. Turns out the battery was exhausted without any warning. The next morning it powered on, showed a "Low Battery" alert then died.

After recharging, the log showed a Low Battery with a blank date, and a Data Abort with a date of "__-___-__ ". There were two previous Data Aborts on 15Aug and 30Jul.

I'm currently running 4.80 and hoping that 4.90 corrects this behavior.

Just bookmarking this thread just in case. Going to do the update!!

EDIT:
Updated, there is now an icon on the map showing how far I am zoomed in. I never had this before.
All seems great.

Thanks for the update, I'll install 4.90 today.

Gook luck to you.

I tested mine again a couple times today and all remains well so things should be uneventful for you, too.

From what I've read, I suppose I should be happy that with the dozen or more firmware updates and half-dozen or so map updates I've done, this was the first time my nuvi needed a hard reset. Even when needed, it's not that tough a task to reset your preferences from the defaults and restore your favorites after a hard reset.

I installed the 4.90 update on a 750. After a couple of trips, everything is working well.

Remembering it was time that showed the problems that lurked in the earlier Garmin update that caused a rather large debacle for Garmin users and the company itself, you should wait to see what happens to those that have gone before you and already made this update.

BTW:
There was no Trojan in the update, as reported in a earlier post above. Just real crappy Firmware programming and poor to no quality control that would check it for errors. Garmin, has us to beta test for them, and doesn't need a clean ISO program.

I myself would wait if I were you! what's another 30 days, heck your GPSr is working except for the battery nag.

Of course most remember this:

Garmin have just made the v3.60 software available via the WebUpdater to fix this "dead GPS" problem. This will only help those who can still power on their 7x5 GPS, others will have to send it in to Garmin with a quoted 15 day turnaround. As a side note some revived their unit by opening it following this YouTube video and disconnecting the battery for 30 seconds, but be advised that this is a risky operation that requires a Torx 5 screwdriver and voids the warranty

I hooked up my 765t and the webupdater found no updates available. The "mygarmin" section of Garmin's website did find updates. Clicked to update, followed all directions, and when complete, still showed update needed. Guess will wait til webupdater shows update for me.

Try MyDashboard on MyGarmin rather than Garmin WebUpdater. For some reason, WebUpdater doesn't do firmware updates.

WebUpdater works just fine for me. There actually has to be a firmware update available for it to actually update your firmware. myDashboard will however erroneously tell you there's a "firmware update" even if it's only a voice update...and whatever it ends up updating (GPS chipset, voice, text/help file, or firmware) it will report that it's "updating firmware".

Stick with WebUpdater. It's at least truthful about what it's updating, lets you see what it's updating and gives you the choice to update it or not. myDashboard will blindly update everything on the GPS, regardless of if you want it updated or not.

I agree with DORKUSNIMROD.I used myDashboard a few weeks ago and it caused problems. Had to soft update my nuvi. It took several time to get it to acquire satalite after the mydashboard update.It updated things I didn't want updated. Gave me no options.

Sever people on Poi-factory told me to never use mydashboard again. They said it had caused problems with several people.
I agree, stick with WebUpdater. It updated my firmward just fine on my 750.

When WebUdater runs it looks to see if there is an update specific for the attached device and if you agree to the update, the download process can be fairly quick. It then goes to the prompt for additional voices, text, etc. The actual firmware update occurs when you next power on the device and you may see "Software Updating" on its screen with a longer than normal startup. It is possible to miss this unless you are watching and waiting.

You can verify the firmware by going to Tools -> Settings -> System -> About. Look at Software Version.

With the introduction of myDashboard, you have a choice to use WebUpdater or myDashboard to install firmware updates. If WebUpdater is truly not updating your device, you may have a bad copy or it didn't install correctly. I've never had a problem with WebUpdater but I've heard of others that have had issues with myDashboard.

I also recall some earlier discussion as to whether it was better to connect the nüvi while it was powered on or off. My recollection was that if it was powered off at connection, you may be prompted to update voices that were already current. I just tried it both ways and didn't see a problem so that may have been corrected since then.

Welcome to the POI-Factory. You've found the right place to find answers and sometimes stir up discussion. The POI files here are a real bonus.

Initially, it seemed to work just fine. In the past few days, I have experienced at least one lockup per day. Typically, several lockups occur together. I have to restart the unit each time. Are others experiencing this as well?

Yes, this is a known issue which is being discussed on other GPS forums as well. Most other folks are reverting back to 4.80 which you can download from http://www.gawisp.com/perry/nuvi/

Glad I stayed at 4.80

Very interesting...but annoying as usual with no 780 specific release (at least they should say 760/780!!!) Garmin's site and it's capacity!!!
