Garmin Nuvi 765T won't power-on or charge

Same problem as another post. Tried car charger and USB charger and my 2-month old Garmin Nuvi 765T won't power-on or charge. I don't have my wall charger with me. Brought it to Florida and am guessing it has something to do with the hot temperature.

Any suggestions?

SOURCE: garmin 765T,dont work/cant charge....

Mine did the same thing. Take a T5 torx bit and unscrew the bottom two screws. Gently pry unit apart. I used finger nails. Disconnect the battery wires from circuit board. Leave unplugged for 10 seconds. Plug the battery wires back into the circuit board. Turn unit on and then plug into computer and run the garmin web updater. Download the fix from garmin. Or you can send back to garmin and two weeks later they'll send you a refurbed unit. You'll lose all your saved data. On top of paying the shipping.

SOURCE: MY GARMIN 765T SAT NAV WILL NOT CHARGE.

Your Garmin is not charging then it is a loose contact or cold solder in charging socket. That is the common problem of socket you must re works the solder there or bring it to a cellphone repair if you are not electronically enclined. If re solder does not fix then problem is in the charging IC. Replaced this IC so it will charged again.

Good luck:

SOURCE: Garmin nuvi 200 pick up charger as a usb cable

The problem is very simple... The GPS unit perceives whatever you plug in depending on the power supply figure.
If you car charger is not giving enough power, then the GPS perceive the cable as being connected to a pc.... thus not charging. Check with an car electrician if you can raise the power supply on your car...

You need to update the software asap. The old version has some kind fault and will eventually cause your Sat Nav to shut down for good.

Will not turn on


Hi Larry -

Your Nuvi 765T should light up when you connect it to your computer's USB port. If it doesn't, there may be a problem with the USB port. Try connecting to the other USB ports on the computer (or a different computer - such as one at work, etc.) if needed. This will help rule out a defective USB port on the computer. You can also connect to a USB charger for another device that you may have instead. It may not charge with another product's USB charger if it provides a very low power output though. The auto plug will not charge the Nuvi when it gets into this condition. Even if it does not light up, leave it plugged into the USB charger / or port over night.

Check the GTM20 traffic receiver plug. It has two LEDs on the body. The one closest to the power cord end is the Traffic Reception Status light and the the one closest to the plug end is the Power light. If either of these lights is on when connected to the Nuvi, the fuse is good. If not not, you may need to change out the fuse in the FM traffic receiver plug. The plug powers both the traffic reciever and Nuvi. Carefully spin off the bright metal ring to disassemble the end to access the fuse. Replace if it is open / blown. If you need replacement parts, they can be purchased from Amazon for about $6.

After charging over night via charger or USB port, disconnect the nuvi from the power / USB cord and turn on by sliding AND holding the power switch in place to turn it on. Keep it held in position for 10 - 15 seconds before letting it slide back. During this time, the Nuvi should start up.

If it will not power up, the battery may be unable to accept a charge. You can replace the battery yourself, but it requires a steady hand, jewelers tools, good eye sight and patience from people selling parts to do this on eBay for as little as $6. Here's a link to those auctions.

If you'd prefer not to do the work yourself, a second option would be to let Garmin handle the "repair". Your 765T is likely out of warranty, and garmin offers a "flat rate repair" fee of $99. If you opt to do this, you will send your 765T to garmin and they will send you a different 765T that has been factory refurbished; complete with the most recent maps available already installed and a gaurantee good for 90 days. Not a bad deal when you consider the cost of upgrading just the maps one time on the 765T. You can start the process on garmin's site, linked here. I have used this service myself and was quite happy with it.

I hope this helps & good luck!

I have 765T Garmin. It won't charge from cigarette lighter. REturned first Garmin to company, got a "newly refurbished" unit, so it's different. Still won't charge from car. Cable lights up,...


if its an oem garmin charger and the green light is on and still wont charge, then the problem is most likely the power port on the back of your garmin...if its not the factory charger, get one for a garmin..that should solve your problem...if not, let me know


let me know if you need more help or info

When using wire in car, Garmin won't turn on, it starts, shows a low battery sign and shuts down. Was working fine on recent trip. It seems no power is reaching GPS. Nuvi 765T


Most likely the fuse in the charger plug has blown. The plug that goes into the cigarette lighter socket has a ring near the end. On most chargers it's silver but some of them are black. If you unscrew this ring the plug comes apart. Be careful not to lose any parts. You'll see the fuse in there. Replace it and it should be ok.
The other possibility is that the cigarette lighter socket is not working. You can check that easily enough by trying something else in it.

It's most likely that the fuse in the plug of the charger lead has blown. There's a ring at the top of the charger plug. Unscrew this and the plug comes apart. You'll see the fuse inside. Be careful not to lose any parts.

1 year old unit simply won't power on, even after connecting to the computer via usb for 8+ hours. Dead as a doornail.


Have you tried the vehicle power cable? That should charge it better and if it does not work then you should contact Garmin or your local dealer.

My garmin 765 T won't turn on- I have charged it overnight


If you are charging your unit with the USB cable STOP - use only a wall plug. The unit will not charge using the USB cable. If you don't have the wall unit - try charging it with the car plug charger for 15 minutes. Just let the car charge it running or not. You will see it work. Once it is charge over half way - the rest will charge up. It is a problem Gamin is working on.

The sound on my Garmin Nuvi 760 does not work anymore, and it will not charge and hold the charge when removed from the car power adapter. I have had it about 10 months.


Please read the article I wrote on this topic.

Also, if your unit will not charge, make sure the charger is ok. Have you tried both car and AC charger? Do not try to charge via the USB as many USB ports can not supply enough current to charge as fast as the wall or car charger.

If your chargers are okay, then I would suspect a defective battery... I have seen this happen before and I have had to replace batteries on several units.
