Plug it in to the computer (usb) for a few hours then try and start it. slide and hold power button for up to 15 seconds till it start.

if that fails, if that fails, unplug the nuvi and turn it off, then press and hold the lower right hand corner of the screen, keep holding/touching lower right screen then power unit on while still holding the lower right of screen until you see the message " Do you really want to erase all user data?" let off power button and remove your finger from the screen and select YES. (this will erase all your saved data) this should reset your nuvi to the factory settings.


use the web updater to update your nuvi once you get it started again.

you can get it HERE

let me know if you need further help.

SOURCE: update problem with Garmin Nuvi 255w

I had same problem. I called Garmin customer service who connected me to a computer rep. Garmin hooks with your computer that you have your Garmin plugged into.They can upload the proper software in no time at all.
The rep told me that after I updated my Garmin I might have turned off the unit before it completed updating the new software. You need to wait until the screen with "Where to?" appears.
It works great now. Prepare to wait on hold for a while. I waited just over an hour on Monday, their busiest day.

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

I can't give you a source of the problem but I can give you at least a temporary solution. Turn the unit on without the cord attached. After it comes up, press on the battery button for 10 seconds until the diagnostic screen comes up. Plug the cord in and press Exit and the unit should work while it charges. You will not be able to use it with the computer using this method, however. To do that you need to plug it in while either without powering it on or after it is powered up normally.

SOURCE: My Garmin 765t won't power on. Anything I can do

Unfortunately, there is not a lot of easy user troubleshooting for Garmin units. I will note that the AC adapter that plugs in the USB port will give the unit more power than a USB connection to a computer or the 12vDC car adapter. If you've tried connecting it to the AC adapter and it still won't come on, it is possible the internal battery has gone bad and is consuming more power than the supply can produce to both charge and power up the unit. You can try leaving it plugged into the AC adapter for an hour or so and then trying to power it up with the AC adapter plugged in.

Let me know what you've done so far to troubleshoot and I'll research some more for you.

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!

Try to soft reset it by holding the power button for at least 20 seconds till it restarts.

If that doesn't help - try a master reset to factory defaults by holding the lower right corner during startup for at least 20 seconds. This will erase all user data and starts the Garmin in factory default.

If it restart I suggest updating the software to the latest version on Garmin.com

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.
