Guys, I can't pinpoint the exact time when my 760 started acting up, but it's essentially unusable at this time. I did an update to 5.30 and installed BaseCamp maybe a couple months ago. I haven't used the Nuvi much since then. I tried to use it in the past week and have had major issues with it. There are a bunch of things wrong. The display get very strange and the device usually freezes up when that happens ( http://i1180.photobucket.com/albums/x414/billsouth/nuvi.jpg ). It often won't boot, you can't turn it off most of the time when it does boot. I can remove the battery and it then acts normal for a brief period. However, the device is essentially unusable now.
I rolled the firmware back and I believe 4.90 is now installed. It doesn't look like 5.30 is even available any longer...at least it no longer shows as an update thru the updater system.
I did have complete back ups of the system files taken when it was new, but that computer was re-formatted and I can't find those files. I did find the maps (2GB) and tried to install those morning but just get a warning message about not being able to connect to the Garmin server. These maps are 2009 era.
I've done a couple hard resets and that doesn't appear to have fixed things. I deleted data, POIs, etc. and that doesn't appear to have helped.
Is this 760 ready for the scrap pile? Thanks for any suggestions.
I think that is your best bet to get your 760 working again. Many times they can access the unit through your computer and correct whatever is wrong.
Maybe "train wreck" isn't a good choice when referring to a GPS. Just sayin'
Sorry if I derailed the thread...
I second the contact Garmin message, that should help resolve the issue. Another option is to find someone who has a working 760 and copy their files over to yours. The map more than likely won't transfer, but you should be able to get it to be operational to the point where you can reload the maps.
Guys, thanks for the replies.
Sometimes I can access the Garmin via the PC, other times it won't mount. I'll check in with Garmin and see if they have any ideas. I'd be happy to get this unit running again.

Been there and done that is my reaction. So let's look at the problem of backup of GPS and phones.
I learned a long time ago that one needs to have multiple backups of data. Just as uber360 experienced, if you need the backup of your GPS but it was on a computer that lost its hard drive and had to be replaced/reformatted and thus is now unavailable, you didn't have enough backup.
One solution is to purchase a USB drive and do a complete backup of your computer every so often. Once a quarter would be good - once a month even better. USB drives are very cheap - less than $100 - and there are good backup software packages that are free (see http://ask-leo.com/what_backup_program_should_i_use.html)
Another solution is to go with an online backup backup provider like Carbonite. Carbonite will in as close to realtime as possible do a backup of any new or changed file on your computer that is in a folder you have designated as wanting the contents to be backed up.
Another solution is to use some software that does realtime backups to an always attached external USB drive. I use one called Instaback2 that was written years ago by PCMagazine. It is still available and costs only $7.99. For any folder that I have specified, it keeps up to 10 backup copies of every file written to that folder on the USB drive.
For my GPS, there is another backup that I keep. A DVD. See Continuing Exercises: Backup Using ISO File
Having done the creation of the ISO file on my computer that I subsequently burned to a DVD, I have two copies of that last Nuvi backup. One on my computer and the DVD. When I do a complete backup of my computer, I have another version of that backup on the USB drive I use for complete backups of my computer and then store back in a fireproof safe. Because I also let Carbonite backup the "MyISOs" folder, I have a "cloud" backup of the Nuvi. I do not ask Instaback2 to backup the MyISOs folder because that creates too much thrashing on my computer as it would try to do it in real time.
Is this overkill?
Well, I do not think so. I lost a hard drive in the middle of a lawsuit. I had a complete backup on the external USB drive in the fireproof safe but because I had been steadily working on the lawsuit, it was 3 months old (and you can imaging how many files you can create in 3 months when you are scanning exhibits every day).
Between the external backup and the Instaback2, I got everything back onto the new computer but it took several weeks to do so. If I had had Carbonite back then, I would have just asked Carbonite to restore everything to the new computer and would have been back in business in a day.
I have lost files on two smartphones before I determined how to keep them backed up.
You may have noted that I am the one who welcomes new members with links to the FAQs on getting a manual and doing a backup. My past experiences suggest that the time it takes to do a backup of anything important (your computer, GPS, phone, etc) may perhaps save you some day.
I did an update to 5.30 and installed BaseCamp maybe a couple months ago.
I rolled the firmware back and I believe 4.90 is now installed. It doesn't look like 5.30 is even available any longer...at least it no longer shows as an update thru the updater system.
Current firmware is 4.90. 5.30 was released about 3 months ago, and then pulled by Garmin. Read about it here:
Good luck, I had to resurrect our 760 when our 1490 died a couple of weeks ago. Worked like a charm (running 4.80 firmware, not much change tob4.90).
Another option after calling Garmin might be to check out a repair company run by another POI Factory member:
Certainly. I totally agree. And i just bought a nice 1TB drive this past week. My old drive is starting to make bad noises.
It's entirely possible I'm going to find the backup. I'd typically keep two, I just haven't been able to locate the disc.
Always seems to be my luck with stuff like this.
I wonder if rolling back to 4.8 would help??
I just finished my 57:40 min duration call with Garmin. They didn't have any further solutions apart from getting a $70 credit towards a fresh unit. They don't support the 760 any longer.
He suggested getting a copy of the "Garmin" file folder from another 760, less the maps, of course.
I'd like to roll back the FW one more step and see if that helps. My unit is essentially a brick now. I guess it's not a huge deal, we've got a couple of 265 units.
The nuvi 4.80 firmware for your nuvi 760 can be found at perry's site:
Thanks! You guys are the best !!
Can we purchase those tiny little screws that hold the case together? I've had the 760 apart so many times to disconnect the battery that both of them are stripped.
It is likely that after the update to firmware v 5.30, the nuvi 760 locked up after about 500 miles in the trip log. It could have been fixed by clearing the trip log. This has been documented in several other threads on POI-Factory.
http://www.poi-factory.com/node/35861 like WASSup says
I had this problem with my 760 after the upgrade to v 5.30. I decided to leave v 5.30 installed and clear the trip log whenever 500 miles was approaching. I recently made a long trip where the trip log was cleared several times and the 760 worked perfectly.
In my opinion, rolling back the firmware is taking a risk. I hope that Garmin is working on a new firmware update to solve this problem with v 5.30. In the event that v 5.30 may still exist on your 760 even though you rolled back the firmware, why not try clearing the trip log?

Thanks for the tip, but I did that a while ago...cleared everything out and there was no change.
If we can't find the specs for these screws, one option is to buy a for parts or as is nuvi:
the trip log when I am returning from a trip. I don't need that info any more.
Try an electronics store. One that does repairs is liable to have some. Rat Shack is a slim possibility, but if you have someone that builds electronic devices you may have better luck. Walking in the front door and crying at the receptionist's desk may get you enough sympathy that someone may grab a few from the assembly line. They buy them by the pound.
Keep an eye on the nuvi specials on Walmart - you might be buying one of them.
...will have an assortment of tiny screws and nuts.
Trust me, the thought has certainly entered my mind
are full of helpful tips today! I do appreciate it.
We've got a very large electronics/hobby store here in the Boston area. They could very well have something. I'll check when I pass by.
I've rolled the device all the way back to 4.20 and it's stable for the moment. 4.90 and 4.60 were not good.
You might want to make things easier on yourself by making sure the screws you do get are not Torx, but Phillips. Also, since the screw holes are stripped, the replacements need to be a bit thicker than the originals to have the screws stay in place within the unit.
I don't think the screws are stripped but rather the holes. The screws are self tapping metal torx head, the housing is plastic. which is softer. The plastic will strip before the screws will. I don't think you need new screws.
To fix you can carefully fill the holes with epoxy made for plastic. Let it dry properly, then use a very fine drill sveral sizes smaller than the screw and drill the holes on center being careful not to go too deep. Then slowly put the screws in, centering them and creating new threads. If too much resistance is felt the holes drilled are not big enough.
One question I have, did you break some of the locking tabs on the casing while opening it?
The locking tabs will hold the casing together firm enough so it won't open.
Yeah, I'd like to replace them with Philips. I may have something tiny like this in my basement.
The threads in the device aren't stripped, it's the TORX hole that's rounded out
No, none of the tabs are broken and it is fairly tight when snapped together. I'd like to have appropriate screws holding it together.
The 760 failed completely yesterday. All I get when powering on is a milky white screen and that's it. I guess I'll write this one off to FW 5.30 and move on.
I'm looking at the refurb 3790LMT at W*mart for $160. Seems like a nice unit at that price point. Does routing still exist on these devices? I definitely going to miss that feature from the 760 and am not keen on the replacement device not having it.
The 3790 has Trip Planner which is a routing function, but significantly different than the legacy multi-point routing engine on your 760. Many users who "upgraded" do not like the Trip Planner, but you can also find those that do. Search this and other GPS forums for "Trip Planner" and you will get lots of opinions.
I looked at the Garmin website and assumed it had taken on a new form which would be unfamiliar to me. Kinda sux. I really liked Routing plus Mapsource capabilities. It's what prompted me to purchase the 760 in the first place
When did Routing disappear? Maybe I should be looking for an older, used device.
If I recall, the Trip Planner was introduced with the 37xx series nuvi. It has been included on the models since then that support preplanned routes (certain models of 1695, 23xx, 24xx, 25xx, 34xx and 35xx series). I think even the newly announced Zumo model has a version of Trip Planner.
If you want to find a nuvi with the old legacy custom routes, you will need to look for a 7x0, 7x5, 8x0, 8x5, 14xx or 1690. There are a couple of others like the 5000 and 5xx, but they are kind of specialized units. The other option (if you have a ton of money to spend) is the Garmin Montana which can do both auto navigation and handheld functions (for hiking, geocaching, boating, etc.)
Thanks again, Allan.
I'm sifting/sorting at the Garmin website. I'm wondering if the 1450LMT might be the right device for me.
with the 14xx series is that they only include 2 GB of internal memory. To effectively do map updates, you will need to install a micro SD card, install all or part of full NA map to the SD card. And if you want the full coverage junction view file, you will need to download and install it separately.
These are not show stoppers since there are effective work arounds, but you need to be aware of the limitations so you won't be disappointed or dissatisfied with the unit.
thanks for those warnings.
I was just looking thru the Owner's Manual for the 1450 and am wondering if routes can be imported from Base Camp, etc. It almost looks like the routes can only be created on the device which makes it less than desirable
Routes can be imported on the 1450, just like your 760. The one caveat is that routes are recalculated on import. It does preserve the start, destination and all via points, so depending on your preferences and via placements, the route is usually preserved.
The 7x0 series was kind of unique in that it didn't recalculate a route on import and would preserve route shaping from Mapsource. I never had a 760, but have read about this in other forums. If you use normal via points for your route transfer, I think you will find the 1450 route import will be pretty much what you are used to.
Alan, that's interesting. Thanks for the detail on it. I guess it should not be a big deal - - I'll just have to keep an eye on it. Maybe I'll be forced to add more via points. I have some highly specific routes I follow when traveling thru DC and NYC region.
As long as you create your route with explicit via points (instead of avoids, "rubber-banding" roads, or other shaping techniques) you should be OK.
That is my technique. I just add a bunch of via points on the routes I want to drive and that has worked well in the past.
Alan, thanks for lending your expertise. I've ordered the 1450 LMT for $130 @ Amazon. As always, I'll be counting the minutes 'til the UPS guy shows up Looks like a smart little device. I'll try to spend some time reading about the comments you made a few posts up concering the SD cards and space constraints.
what size microSD car should I be looking for? I've got a couple of 512MB cards laying around. Will those help me at all?
I'll only use CN, no other maps. Can we load just a part of the country, east coast only, for example? I used to be able to selectively load regions on an old Magellan.
what size microSD car should I be looking for? I've got a couple of 512MB cards laying around. Will those help me at all?...
The CNNANT map file is close to 2GB and tends to be larger each quarter, so given the prices of SD cards these days, I'd go large.
I'd go large.
that's what I figured.
Is there an upper limit that the device won't be able to deal with like 8GB or bigger?
All nuvi models will support SD cards up to 16GB in size.
Not that you've asked, but if shopping, my recommendation is to buy a Sandisk Class 4 card. Amazon and even places like Wal-Mart and Radio Shack at times have very good prices on these in the popular 4, 8, and 16 sizes. Just remember to ensure that you're buying the micro SD card if your device requires micro. I once got so involved in finding the best price that I overlooked this and ended up with a standard SD card
I understand how that could happen. And I've got a bunch of SD cards already. I found a nice Kingston 8GB for less than $8. Hard to beat that.
Thanks for the guidance, Craig
I seem to remember some people finding that HC cards gave them problems while plain SD cards worked.
Is that true?
I don't remember that, but I do remember some caveats from Garmin that their SD card statements applied only to nuvis with current firmware. (This is probably not an issue anymore except for folks with very old nuvis that haven't had a firmware update for more than a couple years or more.)
Other things I remember hearing were issues from folks buying off-brand cards or buying "too-good-to-be-true" cheap Class 6-10 high value cards like the 16 and 32GB from eBay (usually from non-US sellers from across the Big Pond), etc. which turned out to be resales of defective or sales of counterfeit cards.
Folks using their computers to work with the SD cards sometimes found that old computers had issues with the cards using the computer's SD card reader, but the purchase of a cheap USB SDHC card reader resolved the problem.
For the pre-nuvi line, Garmin says:
The following units will not support SD cards larger than 2 GB:
Maybe others have a better memory and can offer more thoughts.
My 660, one of the earliest Nuvi's has no problem reading 8GB Class 4 SDHC cards.
However, the 660 WILL NOT recognize maps over 2GB.
The 7XX series and beyond can recognize maps over 2 GB.
I have bought several SanDisk SD cards on Ebay at god prices. I ALWAYS email the seller and ask if they are genuine SanDisk.If no reply I won't buy from that vendor. I only buy from US sellers.
Once I receive the SD card I go to Sandisk site and register the SD card for the 5 year warranty. You MUST enter serial #, if it's fake it should reject.
I never had a rejection.
If you do receive a fake one, contact the seller and ask for refund. You have proof the seller said it was genuine with your email question on the item.
Here is a link for Ebay describing how to identify SanDisk Ultra Secure SD cards. They don't mention regular SD or SDHC cards.
I would like to put my GTM 20 traffic cable/mount on eBay. Will another user be able to use it? I seem to remember that it had some long serial number sequence you had to enter on the device. I vaguely recall this serial number was on a yellow piece of paper???
I did pay for lifetime traffic on it. I'm fairly certain I have a receipt showing that.
I prefer not to sell the cable if it can't be used by someone else.
I would HATE to have to replace my 760 with a newer unit. When I did have to replace mine I simply found another 760 as the replacement unit. This thing does stuff that NONE of the newer units will do.
I expect that if you go to myGarmin and deregister your GTM 20, then your Buyer will be able to register it in their name and be able to use it. I suggest not selling it and hoping that the buyer will expect to use your paid ClearChannel or Navteq subscription.
I bought my GTM20 from eBay and was able to register mine, then bought a ClearChannel subscription for it. It works with both my nuvi 750 and 855.
I suggest not selling it and hoping that the buyer will expect to use your paid ClearChannel or Navteq subscription.
Craig, you're saying that they'll have to buy a new subscription for it? (Maybe it doesn't have any real value if that's the case ??)
Yes, I think that if you deregister your GTM20, a new buyer would need to buy a subscription.
The one possibility here is that I think some of the GTM20s sold later on came with free ad-supported traffic. If your GTM was an ad-supported traffic device (which you should know since you didn't have to pay for a $50-60 subscription and that you occasionally saw pop-up ads), then your Buyer wouldn't need to buy a subscription. But if you had an early GTM20 that required a ClearChannel or Navteq subscription purchase, then your buyer should expect to have to buy a subscription as well.
I think it's possible that keeping the traffic receiver in your name and account would give the buyer both power and traffic but it's contrary to Garmin's Terms of Service:
Terms and Conditions
Lifetime traffic updates may not be transferred to another person or another Garmin product.
I never had pop up ads on the 760, just on the 265WT units.
I vaguely recall needing to enter some serial number or un-lock code with the 760. I'll have to see if I can find that info.
The GTM 20 is definitely recorded on the myGarmin website.
