Garmin nuvi 765 seen but not recognized

 

Ran into some issues when updating POIs on my trusty nuvi 765.

Previously, when I connected the 765 to my Win 10 machine, a new Explorer window would pop up for both the 765 and the SD card. That didn't happen this time. I opened a new Explorer window and both the 765 and the SD card are there and I can browse the directories of both.

When I run Garmin Express, it shows the 765 as not connected.

I've tried swapping USB cords, ports, and even updating GE to the most recent version. Same results.

In POI Loader, I get the following error message

"There was a problem communicating with the Garmin device (drive name and letter). Please update the software in the device. Communication with the device may continue with reduced functionality. Please contact Garmin customer support for assistance."

The only updates GE shows are some fonts I won't ever use.

I was able to upload POI files to the 765 and they seem to be OK. However, it occurs to me that if this is not corrected, I won't be able to update maps when that time comes.

Has anyone experienced this, and if so, what did you do? Or is it time to start looking for a new unit?

start with simple ideas

Start with simple ideas. Unplug the nuvi. Restart the computer and restart the nuvi. Plug it in using the Garmin USB cable directly into the computer. Start Garmin Express and see if a Garmin driver is installed by Windows.

If it is still not recognized, in Garmin Express delete the 765. Unplug the 765. Shut down Garmin Express and restart Garmin Express. Plug in the 765 and try again for Garmin Express to detect it.

765 not recognized.

See this video https://youtu.be/klKrY2_jwuk . I had this happen to me when I let the charge on the device get to low. Once I charged it back up the problem was resolved.

No luck...

Thank you for the suggestions! Unfortunately, I had no success.

The battery indicator does show 4/4 segments, but it's certainly possible that the battery just doesn't hold enough of a charge. I'll look into replacing the battery.

Thank you again!

That's sad

A few thoughts that may shed some light...or not. Your 4/4 battery level is likely to rule out a battery issue but you could see just how long the GPS will run on battery alone. If the battery level drops to 0 or 1 bar after 5 minutes or so, then a new battery may be worth trying, especially if you want to keep the 765.

I've seen occasions when Garmin Express doesn't see a device while the Windows computer does. Could you run Garmin's POI Loader program and report if it sees the device? When I've seen this, it's with an odder or older device and is a Garmin Express problem. You are using the latest Garmin Express version, right?

Do you have access to a second Windows PC? If so, see if Garmin Express sees the device. If so, then the issue is some computer-related one due to missing or corrupt drivers, etc. Along a similar line, it'd be interesting to see if your computer and cable lets Garmin Express recognize another Garmin GPS. I suppose you don't have a backup GPS sitting around...

You could go to your Windows 10 Apps setting, then uninstall Garmin Express, Garmin Drivers, etc. then start over.

charge the battery

Let's not talk about replacing the battery without charging it first. My nuvi 760 is fine after 12 years with the original battery. Use a wall charger and charge the unit for 5 hours. Then try again for GE to see the nuvi.

Using a USB cord to the PC is not as good, since the amperage is limited and if the PC goes to sleep the USB port will not be live.

Our GPSs run on electricity, and a lack of electricity causes all kinds of problems.

Verify cable type

To emphasize something dobs108 said earlier, use a “Garmin cable”. There are two types of USB cables, one type is for charging, the other for charging and data transfer. They are virtually impossible to tell apart although often the data/charging cable is slightly larger in diameter. Since you say you can “see” the device from the PC, I suspect your cable is the correct type, but verifiy as best you can.

One more thing, when connecting to your PC, plug the device directly into a PC located port, do not use some form of USB “hub.”

My 765t is not recognized,

My 765t is not recognized, or for a brief second it pops up as a drive and just as quickly vanishes. I am curious if you find a fix. I did just purchase the 890 because of our 5th wheel. Hoping that is recognized by our Lenovo yoga 900.

At least I will be able to update via WiFi.

Did you read my comment about type of cable

Did you read my comment immediately above about the type of cable?

If you need to buy a cable, get something that uses the words "charge" and "sync" in the description.

Used same cables I had in

Try a different cable anyway

As a retired engineer dealing with electronics for 50+ years, I can tell you that when the unexpected happened, probably 50% to 75% of the time, the issue was some form of intermittent connection, often in a cable. Since others have already stated they don’t have a similar problem, and a cable is about $7, I again suggest you replace it so you can rule out one more variable.

If you are like me you have a drawer of cables. I believe the 765 has been around since 2008 and as I said it is very easy to get cables mixed up (charging only vs. data synch).

It wouldn't hurt

It certainly wouldn't hurt but the OP states that the computer sees the device and files and that the Garmin POI Loader program works (at least, the OP states that custom POIs can be uploaded and used), so I'd be surprised to see a cable that fails with GE but works with Windows and POI Loader.

I normally would agree with you 100%

CraigW, I normally would agree with you 100% but we are at a point where we have to rule some things out. I see for instance that the OP has also said he has tried several different cables. But a new and proper cable should perhaps be attempted, especially in light of the low price. To share an experience, I have a 265WT that gave me similar type operation; not any error message, but just intermittently would not be recognized in GE or by Windows. A new cable seemed to affect the behavior but it still wasn't 100% reliable. I noticed that if I had it screen up when connected to the computer, it would act up while screen down it would rarely act up. Some online content seemed to indicate the connector on the 265 may have been the issue. I opened the case and did a quick hit of solder on the connector and it has been fine ever since. One reason it perhaps never or very rarely acted up in the car, is I always wrap excess cable from the charger around the mount to relieve the weigh of the cord from the port on the back of the GPS.

Something we also don't know, is the capacity of the SD card being used and how much free space is available.

Speaking of cables

What cable can I use to allow me to plug my Garmin 1450 into a wall plug to have it charge.
