Nuvi 660 will not hold a battery charge. - Garmin Nuvi 660 GPS Receiver

Make sure the fuse to your DC socket isn't blown. Check the fuse in the tip of the charger. When your Nuvi 660 is plugged into the cradle, you should see a yellow lightning bolt over the battery icon. If you don't see this, then your Nuvi isnt getting voltage from the car charger.

You can also have a bad cradle or charger plug that plugs into the cradle. More info can be found here:

When you leave a Nuvi on a charger for several hours and don't see full green bars, this is an indication that the battery is defective. Most Nuvi batteries last about 2 years. Most of the batteries have a date code of 2007. I would have the battery replaced as soon as possible as it can bloat and crack the case open. More info can be found here:

The real question is this:

1. When you plug the Nuvi onto the cradle, do you see a yellow lightning bolt appear over the battery icon at the main menu?

Compare it with the AC charger. If you don't see the lightning bolt, then you either have (2) problems:

1. There is a problem with the car charger not feeding power to the Nuvi.
2. There is a problem with the rear cradle socket on the Nuvi.

I have fixed both problems before. More info can be found here:

It sounds like your battery is defective. They can be replaced. The Motorola phone cable is not wired exactly like the Garmin, and your Nuvi thinks it's connected to a PC. Radio Shack carries a charger for the Nuvi. I have one myself.

Let me know if you need additional help with your battery problem.

replaced battery. works fine now. holds charge for some six hours or more.

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
