Garmin nuvi 760 won't stay on

I saw your advice to Missy regarding her gps and how it might be the cable. At any rate, my GPS won't stay on after the "loading maps" message. Shouldn't it power on when connected to the car adapter with car running? Also, when I connect via USB to my computer, I get the Garmin logo and USB connect icon but nothing else. After trying to reset it, I don't see anything but a black screen! My question is...can it still charge while off?

    unit charges fine from USB, appears to work perfectly in other respects. However it does NOT appear to charge while plugged in with auto adapter. I Have tried on a couple differant cars.



    There are two lights on the auto adapter, the top one (red) will come on while plugged into Garmin to do traffic updates (i think), but the battery charge icon never goes away, which leads me to believe it is not charging. I have no way i can tell if the Garmin unit knows it's plugged into auto adapter. Anyone with any ideas, much appreciated.

SOURCE: Garmin Streetpilot i3 GPS cannot load map to memory card

The Garmin C340 comes preloaded with maps while the I3 require that the maps be installed onto a micro sd card.

You can place the micro SD card into a SD adapter and use a regular card reader to download your maps. When the software ask for 'Device' to download to use the drop down arrow and find your drive letter associated with the card reader. Using a card reader will be much faster since the it is ubs 2.0 vs ubs 1.1

You could also go to Garmin website and download and install the USB drivers, see link below.

Sounds like you both have a battery problem. I experienced a similar problem when trying to charge via the USB-cable connected to my computer.
Ended up buying an original charger (expensive) and the charging went smooth.
The car charger should in any case work fine, so probably your battery is not very healthy.

Try holding your finger on the battery symbol for about 10 sec. The unit will then switch to a technical page. There you can observe the battery and charging voltage. When I plug in my computer USB-cable, I read around 4,4V and that is not sufficient for charging my battery.
When connected to the original charger, this voltage rises to about 5V which gives a nice charge. When unplugging charger, the unit displays the battery capacity. If the charging voltage is OK, but battery capacity drops quickly after you unplug charger cable, the battery is probably bad. (Of course you have to charge is for some time) I think around 4V battery voltage give 100% capacity. 3,9V gives about 90% capacity.
This will not solve your problem, but can give you an idea about what is wrong.
Good luck.

You must call Garmin at 1-800-800-1020 they will walk you through plugging in nuvi to your computer (must have usb cord) and it will upload then go to my computer and choose garmin drive then click garmin folder and either find the folder they say or make new one like I did with the guy on the phone and put in code. The only information needed is the numbers on the bottom of the device.... super fast fix!

No sign of life from my gps


From Garmin's website:

  1. Make sure you are sliding the power button all the way to the left.
    • If the unit does not respond, it may be that the battery is not charged.
  2. Connect the nuvi to a power source such as the USB cable and your computer.
  3. Reset the device, if the problem persists, by sliding the power button to the left and holding it in that position for 10 seconds
    • This resets the unit and prompts it to power on
If still unable to breathe life into your 760, contact "SUPPORT" at www.garmin.com. Please rate this reply if helpful - good luck!

You may benefit by going to Garmin's WebUpdater page to download & install updated firmware on your nuvi 760. It's free and all you need is a computer with a USB port and a USB cable that fits your nuvi 760 (it was included the box) The directions are clear and it is very easy to do.

Good luck!

Garmin Nuvi 760


I have the same unit. It comes with a trial subscription and then there is one time fee. The traffic will ONLY work when it is plugged into a power source in the car.

Remember to turn off the unit before you disconnect the cable. Otherwise the GPS unit will stay on and drain the power.

Nuvi garmin gps got wet accidentally


Try putting it into a ziplock bag with silica gel packs or else uncooked rice. This might wick more of the moisture out. If it doesn't fix it, you'll have to send it in for service.
