Re: Garmin 760 will not power on
Are you using a USB cable that you got from Garmin? You might have to buy their cable, as opposed to using one that you already had lying around. There are tons of people having issues like this. Garmin doesn't include the USB cable with the unit. Your camera cable has the same style of plug, so you hook it up - and then the weirdness starts. Some people get lucky and it works, while others find symptoms as described above. Garmin really ought to include a USB cable with the device if a special one is required. This is giving them a black eye whether they realize it or not.

Same happened to my Garmin Nuvi 760, power failed during upload. Files corrupted. Garmin could not locate it with Sat. Told me to trash it and they would give me $70 towards purchase of a new one, which would not fit in my cars receiver. My solution was to purchase a used one that had a good Garmin File folder. I copied the folder to my pc. It was important to remove the device file from the copied folder. I then formatted my corrupted 760. Then copied the folder from my pc into the formatted 760. Next step was to use Garmin Express to replace the missing device file, do the updates, and reinstall the maps. Product code to unlock maps was inside the rear plastic housing to unlock the maps. Whole process took about 4 hours and it works like new now.
I own a Garmin also, my suggestion is plug it in to your computer, leave your computer on so it can charge up overnight. If in the morning it wont power on my suggestion would be to contact Garmin you may have a bad battery or some other internal problem. Garmins web site is www.Garmin.com Contact there Tech department to see what they would charge you to check out your unit. It has to be cheaper than buying a new one.
I hope this helps you out if so leave me some feedback.
Is the battery charged? What does the battery indicator say? If you are
using it in the car, is the power cord connected and working properly?
If it is working correctly, you should see a lightning bolt symbol over
the battery bar graph showing that it is connected to an external power
source and that it is charging. Try plugging it into your PC
and looking at the battery indicator. Do you see the lightning bolt?
Does it shut off
when your using it on the PC? If not, there is something not right with
the car adapter. Also, just because it was plugged into the car adapter
does not mean it was charging. Many cars will turn off the cigarette/accessory jack when the ignition is off or shut off after a
short while to protect the car's battery from being run down. Try
hooking it up the the PC overnight and leave the PC on. In the morning try using it. Does it still shut off? If so, the internal battey
may be bad. If it works and doesn't shut down, you have a problem with
it not charging in the car and the adapter may be bad.
folks, the garmins have an on-board battery that needs to be powered up (at least occasionally) via the usb port - like from your computer. just using the dc car power cord does nothing for this battery. i've had this exact same problem on both my 760 and 780 nuvi units. fixed it using the usb charge. seems to run down differently for all the various nuvi models. my regular charge will hold for 7 hours on my old 660, my 760 and 780 work about 5 hours. my 'power up' failed on the 660 after 10 months with no internal battery charge, but the 7xx models only took about 5-6 months to 'fail.' hope this helps. jack b :-) in midland, tx usa
