You need to purchase an AC wall charger. Make sure it's a Garmin. There are too many after-market units out there that are not wired correctly and will cause your Nuvi to think its connected to a PC.

My Garmin Nuvi 780 will not stay charged. also i am unable to charge it while I drive.

The Nuvi 780 is an older GPS. Most likely, the battery needs to be replaced due to age. Many lithium-Ion batteries are only good for 2 years. More information can be found here:

Please have the battery replaced by a professional. We have repaired many units from failed battery replacements by customers. Often other things get broken in the process, sometimes beyond repair.

Possible bad battery---are you charging with the lighter plug in the vehicle or what? That plug it uses for the lighter will have a fuse inside it in most cases.........

Why won't my Garmin Nuvi 780 charge?

A couple part answer here. The USB pin out for the Garmin is strange. If it goes into PC mode, then the cable is got the wrong pin out for the unit. Try different cables until one works.

If you can get a full charge on the unit and the battery does not provide at least an hour + of battery use, then the battery needs to be replaced. Amazon sells replacement battery kits with instructions. You just have to make sure you order the right one.

hi danielktx, its doing that because it thinks the charger is the USB cable and connected to the computer...either you have the wrong charger (is it factory or after market) or the charger it self is faulty.

I checked your unit under Garmins recall section and your unit has not been recalled for battery issues. If you enoy your units MP3 feature and FM transmitter I would recommend sending it in for warranty. Otherwise it may be cheaper to purchase a new unit.

Hope this helps!

I had the same problem. When you have your nuvi plugged into your cigarette lighter it doesn't charge. Your battery is probaly near dead. I called Garmin and they told me to plug it into my computer via the usb cable. Turn the Garmin off and let it charge for several hours. That did the trick

Garmin nuvi 780-when recharging the battery should the user know when it is complete and how long should it take?

Hello skatecat,

The Garmin Nuvi 780 GPS receiver should take about four hours to fully charge. You can review the charge status by checking the battery icon in the top corner of the GPS's menu page.

Best Regards,

Garmin nuvi won't turn on

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
