I have a Nuvi 285WT. The battery must have run out of charge before I plugged it into the car and now it won't take a charge from computer USB or regular wall outlet sources. The only thing I can get is a flashing 'Garmin' logo every 10 seconds or so, then black screen.I have a Nuvi 285WT.

Yes, the fuse in in the end of the charger that plugs into the cigarette lighter. Be careful when you unscrew it as there is a spring in it. Replace the fuse if burnt out with an exact match.

You need to determine if it is a charger problem or a problem in the Nuvi.
If you have the AC wall charger, plug that into your Nuvi. If the unit boots normally, then you can discount that there is a problem with the Nuvi. Does the Nuvi power up on its own internal battery with the charger disconnected? When you change the fuse and it blows, is the charger plugged into the Nuvi?
Try changing the fuse and powering up the charger without it being plugged into the Nuvi. If the fuse still blows, then the fault is with the charger. Please also be aware that the charger converts +12VDC from the car battery to +5VDC to power the Nuvi. Some chargers can fail and provide +12VDC directly to the Nuvi. This can damage the Nuvi and will certainly blow the fuse.
When the charger is plugged into the unit, look at the main menu screen. If the charger is working correctly, the green battery icon in the upper right-hand corner eill go out. If the charger is plugged in and there is a light lit on the charger but you see the green battery icon in the upper right-hand corner of the screen on the main menu, then the unit is on battery power and the battery is not getting power from the charger. Common problem with these units are loose rear USB ports. More information can be found here:
If a wall powered charger is used it could be bad or the connection from it to the unit damaged---happens if the charger is connected/disconnected a lot----same thing can happen if using the lighter plug adapter for charging.
Probably a burned out fuse on the power cord. Unscrew the end of the 12v plug and check the fuse with an OHM meter or just replace the fuse. Check that you have 12volts at the gps end of the cord.
TRY CHECKING THE FUSE IN THE END ON THE GPS CHARGER, THE TOP WITH SPRING LOADED TIP UNSCREWS TO LOCATE IT, THAT IF YOUR CAR LIGHTER IS WORKING, TRY A USB /MINI USB FROM YOUR PC/LAPTOP TO SEE IF THE GPS UNIT IS ACCEPTING CHARGE
Had the same problem with my Garmin Nuvi 260w. It just needed to be reset. Lift up the sticker strip on the bottom of the unit and press the reset tab. Worked like a charm for me. HTH!
It sounds like a dead battery?
When it is plugged into the car, you should see a charging symbol, or it will say charging if the screen is off.
Are you sure it is getting power from the car? Check the fuse for the lighter socket, also the power cord has a fuse in the end that goes into the cigarette lighter socket, if you twist the end of the adapter it should open and expose a fuse.
Check these fuses to be sure.
Yes, you need to charge it. USE the charger that came with it for best results. Some off brand chargers will NOT work. You plugged it into your car and nothing? Even if the batteries are bad it should still work. Is it the Garmin charger?

If your unit will not charge in your vehicle, you may need to replace the
fuse located in the tip of the vehicle power adapter.
Unscrew and remove the silver
or black, round end piece.
Got a Garmin Nuvi 260. Same problem. I read the booklet. There's a reset button on the bottom. Disconnect from power. Push the reset button. Connect back to power. Now it works. The reset button is tiny and looks more like just text on the bottom sticker than it does a button. But push it anyway.
