The unit will charge off of the usb on the computer. But it will not charge off of the stand plug in or the regular car plugin. I have tested both chargers in two diferent cars and they both have dual plug in for devices. And both car accessory plugin untis work with my other devices (cell phones ....) any suggestions?

Re: Garmin NUVI 660 power problem.
To charge a nuvi, use one of the following methods:
Connect the nuvi to the suction cup mount and the vehicle power cable.
Connect the USB cable to the nuvi and the computer. The computer will charge the nuvi as long as the computer is on. However, the unit will be in Mass Storage Mode and normal operation is not possible.
Connect the AC power cable and the nuvi to a wall outlet.
Please note: All of the nuvi series will come with a suction cup mount and vehicle power cable to charge the nuvi. However, only some of the nuvi models will come with an AC power cable and/or USB cable. If they did not come with the nuvi, they would be optional cables and would be a separate purchase. Garmin only recommends using an AC power charge that is purchased from Garmin. Third party power cables may not charge the nuvi. These cables may be purchased from Garmin or Garmin's dealers.
There's a 1amp fuse in the end of the car charging jack. Did you check it? (I think the LED won't light, if the fuse is bad.) Just unscrew the end of the jack that goes into the cigarette lighter socket and you'll see it. Open it slowly, there's a small spring inside that presses on the end contact. If you press on it before unscrewing the tip of the plug, you'll feel it spring up and down.
Hi, sounds like the problem is where the mounting cradle plugs into the Nuvi. Basically, there are 4 copper pins at the back of the Nuvi for the mounting cradle. These in turn are spring loaded onto the motherboard inside the Nuvi.
It is possible that the tension is not suffcient to hold these pins onto the motherboard
Not the easiest of units to dismantle, but a 5 minute job once the Nuvi is open.

You will need to reset your Nuvi as it is locked into computer mode. To reset it - depending on your version see below.
On some Nuvis there is a recessed master reset button on the body of the unit which you need to access with a nib of a pen or bent paper clip.
For Nuvi 660/680 series
Power off Garmin unit. Press and hold the upper top left corner of screen and then power on the unit by pressing once on the Power button. You should be prompted to clear all user data, or asked if do you really want to start up in maintenance mode. Press “Yes” to reset (warning: all data will be erased and lost, so backup before proceeding) or enter maintenance mode.
For nuvi 200, 250, 360 750, 760 series
Turn off Garmin device. Press down on bottom right corner of the touchscreen, and while holding it power on the GPS unit. You should be prompted whether do you really want to erase all user data, or asked if do you really want to start up in maintenance mode. Press “Yes” to reset (warning: all data will be erased and lost, so backup before proceeding) or enter maintenance mode.
If the above fails it is likely that the problem is not with the Nuvi but the charging unit which is not signalling the unit properly and the Nuvi is recognising it as a USB cable instead of a charger.
Hope this helps. Please remember to rate my answer. Many Thanks.
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.
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
