Windows 7 will not connect to Garmin Nuvi 765T

Did you try without the USB cable connected to a cradle? Instead run usb cable directly to the device.

To check the computer's recognition of the device on a Windows PC click on the Start menu and select (My)Computer. The device will show in this window if the computer recognizes it. On a Mac, the device will show as an icon on the desktop, labeled "GARMIN", or it can be found by selecting Finder from the dock and viewing the device list on the left-hand side menu within the window.

Note: If the computer still does not detect the device, try plugging it into a different USB port. If the problem persists, try another computer, if available. Ensure the USB cable is not connected to a cradle, if one is attached to the GPS.

Ensure the cable is a compatible USB cable. https://goo.gl/G6xpfI

The cable is not connected to the dock, it doesn't show up in my computer or windows explorer. tried all my USB ports, direct and adapter ports Also the same cable works on the third computer.
Thanks

It doesn't seem reasonable that 2 of 3 computers would all of a sudden stop seeing the device.Something changed somewhere. I would still try another USB cable.Below was a problem one member found but it should not apply to you. It does speak of a power problem issue that may be considered.Do you have more devices attached to the 2 computers?

One problem and solution reported by POI Factory member JD4x4 was that some newer Garmins seem to require a bit more power on the USB port than other models.It may show the PC connection screen, but will fail to be recognized by the PC (especially a newer tablet and/or laptop).JD4x4's solution was to purchase a USB hub that supplies it's own +5v power.

The power problem referred to could be it. Have you tried charging your nuvi? If not I would do so and try again to see if that's the issue.

Like charlesd45 says something must have changed.

Once you have tried out the suggestions and you feel all the troubleshooting issues have been tried. Looking at each computers and when they have been updated.Go back to old reliable and set your computers back to a earlier date for recovery that you know had no problems with this issue.If all updated same time then that would not apply.

One possibility is that the internal memory in your device is full or nearly full and the device is unable to do a clean boot cycle or create a fresh copy of GarminDevice.xml. Try going into the menu and delete the trip log, Doing that will generate a smaller current.gpx file and may open up enough space to get around the problem. It may not help, but is worth a try.

Another thing to try is to remove the SD card, then try connecting to the computer without the card installed.

The 765 is old enough the battery may be failing. Try charging it with a cell phone charger that plugs in to 120v, for about 5 hours. After charging, the USB port may be strong enough to power the 765.

Garmin Express will install USB drivers for the PC. Run Garmin Express and click on the icon for the 765 and delete it from Garmin Express. Reboot the PC with the 765 unplugged. Start Garmin Express. Plug in the 765 and it should be detected. Garmin Express then installs the Garmin USB drivers.

I had an issue with my Win7 computer suddenly no longer recognizing my Nuvi 760. Turned out to be a drive letter conflict. My Nuvi used to be recognized as Drive G. Computer suddenly couldn't see it any more. Turned out I had added a USB backup drive and it got assigned Drive G first and for some reason it did not assign a new letter to the Nuvi when I plugged it in.

The fix was to go into Computer Management/Disk Management and manually assign a new drive letter to the backup drive, as well as the Garmin.

Have you by any chance added another USB device to your system?

I think johnc has brought up an important point that explains why the PC might forget about a nuvi that worked previously. We have helped posters here fix that problem but the root cause was unexplained.

Thanks, johnc

I also have a 765T and had no issues with it on a Win7 PC or on my tablet (the one that had the RV660 problem), but dobs108's suggestion about a failing/under capacity battery is a good one and one that a powered USB hub might solve. My 765T also has a new-ish battery from the Garmin battery recall.

Otherwise, your "searching" problem sounds just like the problem I had with my RV660, and a $20.00 powered usb hub from MicroCenter resolved it.

Thank you Johnc, this seems to be the problem, gave the Nuvi a "drive letter of G:" now Windows will recognize it. But Windows want to format the drive before I can access it. I will keep playing with the settings until I can read it.
Thanks again.
And thank you to everyone that answered my plea.

How helpful can Windows get! It wants to format the drive so you can access it!

dobs108

let Windows format the 765(I have a backup, copied all the files when I did the backup!
The 765 seemed to work fine, except no voice, had alert tones. Plugged it back into the computer, windows wanted to format it again. Windows goes thru the format, but it dose not format the gps, after I run the format I can disconnect it and it works the same as it did before the formatting. So windows says it is formatting the gps drive but it isn't. All 3 computers do the same thing. If I try to access right after the so called format and copying the files from the backup windows says the "system files" are not found so it is an unknown drive. I have tried other usb cables also. Can't see sending it to Garmin, will cost more than replacing it. Currently looking for a 765T on Ebay. If anyone has any ideas I am open to try anything.
Thanks

Looking for a cheap 765T or similar GPS for sale. Can't seem to figure out the problem with the one I have now.
Thanks

If you think it might be a bad speaker, you could contact Jim at Sharcnet for repair potential. Note that Sharcnet is a POI Factory member and has his contact tab enabled.

If looking for a replacement, I suggest something newer than a 765 unless you have some reason for sticking with that model. Remember that a replacement 765T will not come with lifetime map updates while those below (anything listed as LM or LMT) come with lifetime maps.

I'm pretty sure the 765 came with a powered mount and I think it likely that you will continue to prefer that. The nuvi 2460 comes to mind as a potential inexpensive model, quite cheap on ebay now, and with a powered mount:

http://www.ebay.com/sch/i.html?_from=R40&_trksid=m570.l1313&...

A quick check on eBay shows the 2460LMT to be offered at about the same price as the much older 765.

The split-screen junction view on the newer models is an improvement over the short-duration full screen junction view on the 765 and a real reason to upgrade. Also, if you have a smartphone, a model that offers the Garmin Smartphone Link is worth looking into.

Very many here are happy with Factory refurbs with a Garmin warranty, a safer bet than buying used. Some good examples under $200:

$120 http://www.poi-factory.com/node/46099

After rereading your original post, I see that you are getting alert sounds, so what I said about a speaker failure is incorrect, and a hardware repair won't help.

I have to agree with CraigW here (I most always do by the way ). By the time you get a used 765T, even if it is really cheap, and add the lifetime map subscription, and most likely a new battery, you will have more invested than a good refurb device that is much newer. IMO, it doesn't really make sense UNLESS the mp3 player/external audio jack are very important to you. Beyond those features, there is very little reason to put money into a device that old.

I understand the idea behind your post, alanb, but you know, at times, it gets to be a "ME vs. IT" senerio.....

When my 660 rear interface stopped working, that's exactly what it was with me.... I'll be damned if this thing will end up in the trash heap...

Once I determined that it would run off USB connection, and replacing battery didn't help and re-seating cables didn't help the rear interface..... with an 'altered' USB cable, SD Card Maps & Music, and it working now... I knew then that I'd keep it as a backup (In wife's car being used, right now!)

Scrambled directory, broken rear interface be damned! As long as I can load new maps on the SD card (Thank You! ! ) and POI's... This old clunker will continue On, and On.... Until........

What is a "rear interface"?
