Question about Garmin nuvi 765T GPS Receiver

Open Question

Error updating maps on 765T. Now won't turn on.

I just received my 765 on Thursday. I was attempting to update to the 2010 maps on my Mac (10.4.11) and it got part of the way through the update, then said there was a problem with the update and it couldn't finish. I believe it had index code -4. I was pretty tired, so I decided to deal with it later. I attempted to un-mount my Garmin, but it kept saying it was in use, so I kept it plugged in. I didn't think much about it, and closed my laptop to go to bed. When I did, the Garmin said system unavailable. I reopened my laptop and it had the device removal error, even though usually when I close the laptop the devices stay connected. I unplugged it and plugged it back in and it no longer recognizes it. Garmin's site said to try a reset, so I did, but now I can't even get it to power on. Is there anything else I can do to get it to turn back on? Customer support is closed until Monday, and I have a big trip I'm going on on Tuesday, which is why I bought the GPS now. Thanks in advance for any help you can give.

SOURCE: 2009 map update not loading

Fixed. Called Garmin. It seems that version 4.90 FW on the Nuvi 350 (which came shipped on my 350) has a bug where it cannot communicate with the Garmin software either to update maps or update FW. Tech from Garmin e-mailed me a patch that I copied into the Garmin folder on the Nuvi itself, via USB and Windows Explorer. I then rebooted it; the patch installed itself which then allowed the unit to communicate with the map upgrade software and all is well. 2009 map update is now installed and the Nuvi is working fine again. Haven't tried upgrading to newer FW yet; will probably leave well enough alone.

SOURCE: SISTEM SOFTWARE MISSING on my Garmin NUVI200 GPS

All Garmin users,

There is no easy solution for this except to return your unit to the nearest Garmin outlet. You need to have very special equipment called an E-Prom burner or writer which only Garmin have. With this equipment they re-programmed (restore) the operating system back on your specific Garmin unit and model.

The problem why anybody can't do it is because there is no way you can access your Garmin unit from a pc or mac if the operating system is lost or damage on your Garmin, for the simple reason your pc or mac can't reconize the device that is pluged in, because there are no communication platform between the two devices.

As simple as that, life with it or send your Garmin gps to an autherized professional Garmin dealer.

SOURCE: Webupdater won't detect Garmin unit

I have the same problem of the Nuvi 850 being recognized by webupdater. I downloaded 4.30 firmware update using this link http://www8.garmin.com/support/download_details.jsp?id=4043 plug the unit in and ran the update. It will ask you to disconnect once it is done. The unit will boot up after a few update progress bars. Plug it back in and launch webupdater.

Enjoy,

Fellow 850 owner.

Hi,
Take a look at this site, http://www.garmin.be/missing.html Download and unzip the software, plug your garmin in the USB and start the updater.exe program. It gets you started again. Later on you can use the Webupdater to get possible newer software..
It worked for me and my Zumo550
Goodluck

New garmin - got latest updates from garmin loaded it then it says maps not unlocked?


Garmin only allows you one free update for your GPS as long as you download and install it within 60 days after you purchase your unit. If you have tried to download any updates after your 1 free update without paying the update fee you would get the error you have mentioned. If this is your first update, or you have paid for it, and you are getting the error, the map has become corrupted. You'll have to contact Garmin's support and they will have to supply you with a code to use to unlock the map.

Garmin 765 turns on and sais loading maps then


I've had this issue on my Nuvi 1300, where holding the power button for 10-15 seconds would restart the unit, but it would freeze at the "loading maps." part. I ended up plugging the unit into my PC, which started it for purposes of data transfer. I then disconnected it from the PC and it restarted properly.
Try that out and see if you have any better luck.

I tried to update my garmin. The screen doesnt move (or continue to download) I allowed for block ups.


You need to download and install the Garmin WebUpdater and Garmin Communicator Plugin both available from Garmin's website onto your computer. This allows updates to be installed directly to the 765T and provides the necessay USB drivers as well. The 765T must be connected to your computer when performing all updates or upgrades.

You may need to create a MyGarmin account and register your Nuvi 765T.

Resetting the 765T: with the unit off, press your thumb or finger in the lower right corner of the screen while turning the 765T on. This will clear all user data, base map software will remain intact. Connect 765T to computer and proceed with the Garmin WebUpdater.

My nuvi 765 will not turn on. Any solutions? How do you reset it? Vista will not even recognize the Garmin in the USB port. I'll assume that it's because it can't communicate to the OS. :) It just shows...


Resetting the Garmin Nuvi 765T: Press and hold your thumb or finger in the lower right hand corner of the screen while powering the unit on. This will erase all USER data, base and detailed maps will remain intact.

Connect your Garmin Nuvi 765T to your computer via USB.
Download Garmin's Communicator plugin and WebUpdater, both applications can be downloaded from their site. By doing so, this will load the necessary USB drivers to your computer, allowing the Garmin Nuvi to communicate and update firmware and software via the plugin and WebUpdater.

On Vista, the Nuvi 765T appears as Garmin Nuvi without the "T" as well, (a blue triangular icon also appears) it does not affect the ability to transfer files or explore the device in any way. If you load an SD card into the Nuvi 765T, it will appear as a removeable disk and assign it a drive letter, in my case H:

My Garmin 765t stopped navigating


There should be a small reset switch on the back of most garmin gps units. with the unit on, depress the reset switch with a pen tip or small object until the unit shuts off and restarts. It may take a little longer to pick up the satellite but it will reque the unit and unlock the navigation screen.
