I have a garmin nuvi 765 and the screen does not come on at all. it worked fine before this. I dont use it a whole lot but i miss it...i tried plugging the unit in different vehicles, thinking that something was wrong with my cigarette lighter, but it never lights up now. Is there another way of testing it or is this 2 year old model(hardly used) broken forever?

Did you get this working? if not, try connecting to your computer's USB port over night and turn on again. Install in the cradle in the car - if it goes out or none of the traffic receiver's LEDs do not light, check / replace the fuse in the tip of the power plug or the cigarette lighter fuse in the car's fuse panel.

SOURCE: the sound on my nuvi

The fact that it appears on speaker, FM & headphone jack, tells me its a problem in the audio output stage.

SOURCE: garmin nuvi does turn on when connected to power in car

Hi

I had the same problem. My Nuvi 350 did not power up for a couple of days. I suspected moisture to be the culprit. So I took my wife's hair dryer and blew hot air(in the intermediate setting) into the SD card slot in the GPS for a couple of minutes. Take care not to overheat the GPS or Screen.
Pronto my GPS powered up without any issues.
Hope this helps

SOURCE: Garmin Nuvi 765will not lock on to satellite.

Download & install the Garmin Web Updater for your computer from their page at:

http://www8.garmin.com/support/collection.jsp?product=999-99999-27

Connect your nuvi to your computer with the USB cable and allow the computer recognize it.

Run the Web Updater program and follow the prompts to update the GPS. When completed, remove the GPS.

The first time that you connect the GPS to the traffic receiver, the GPS will update the software in it. It may take a minute or two to complete. If you have any problems, you can contact Garmin Customer Support at the numbers below:

SOURCE: Garmin nuvi 250 powers on, shows loading maps then

try connecting it to your computer via the USB cable, sometimes that will reset it. If not, you may have a warranty issue.

I plugged in my garmin nevi 1350 into my computer for updates, and it's not showing up on the screen (MAC). The update program can't find the device on the screen. What am I doing wrong? marilyn

Perhaps nothing.

Does the GPS turn on and go into usb mode when plugged into your MAC? If not, it is probably a driver issue if the GPS works normally in your vehicle. You might try the Communicator Plugin for MAC. https://www8.garmin.com/support/download_details.jsp?id=3739

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.

How do i switch to pedestrian mode on my garmin nuvi

From the main screen, press "Tools". Then "Settings". Then "System". Change to pedestrian mode under "Usage Mode" This is how it is done on my Nuvi 765 T. I believe it should be similar for yours as well.

The Garmin 765 does not power up when turned on whether or not it is plugged in. The screen is totally black. I have had it since September.

i had a simlar problem with mine, i replaced batteries, which didnt work, then tried the in car charger, which didnt work. i eventually found it was the power plug that came un soldered inside. repaired with a little solder and soldering iron

I forgot my password for my garmin nuvi 765 its been such a long time i dont remember :(

Do this by pressing and holding the bottom right corner of the screen while powering up the unit. Hold the corner of the screen until the message window "Do you really want to erase all user data?" pops up and proceed with your choice.
Reenter info.
If that doesn't work, call Garmin customer support @ 1-800-800-1020
