Magelllan GPS Good morning. On my Magellon GPS (that I plug into the cigarette lighter in car) I plug it in and it comes on for a minute then shuts off. I wiggle the cable at the magellon end and it comes on for a second. I went to radio shack and got a new cord, same thing, use my house cord and same thing. The little pronge in the unit does not feel loose. Any suggestions? Thanks, Scott

Most cigarette lighter circuits can handle up to 20 amps of current draw. Go over that and bye bye fuse...The lighter itself will draw 10 amps when it creates a direct short to heat up. As you can see. a 5amp is useless.

There's a fuse in the plug that goes into the lighter that may be blown.

Most likely the fuse in the charger plug has blown. The plug that goes into the cigarette lighter socket has a ring near the end. On most chargers it's silver but some of them are black. If you unscrew this ring the plug comes apart. Be careful not to lose any parts. You'll see the fuse in there. Replace it and it should be ok.
The other possibility is that the cigarette lighter socket is not working. You can check that easily enough by trying something else in it.

Found a cigarette lighter assembly that is the standard DIN/SAE size that is a direct replacement for the one in my car.

Buy a adapter for your cigarette lighter socket that has multiple sockets with one that will fit the Garmin adapter.
I've never heard of a problem you are having??
Are you using a Garmin plug?
If not get one.

One hour is about the time the unit will run without a power source.

You need to check that the cigarette lighter is working. Check the car fuse.

Check the fuse (one of the six bumps) on the cigarette lighter plug has not blown.

Is the cigarette lighter / Tom Tom lead damaged in any way?

This is telling me that your cigarette lighter socket has +12VDC applied to it all the time EVEN when the ignition is turned OFF. This is not the fault of your Nuvi. On some cars, like Hondas, the cigarette lighter socket powers off when your ignition is turned off.

If you want it to turn off with the ignition, then you will have to power it from a +12VDC source that is controlled by the ignition.

You should be, Check to make sure the fuse isnt blown on either the cigarette lighter plug or in the plug that has the wires coming out of it.

Verify that the car cigarette lighter outlet is working. Do you have something that you could plug into the lighter like a light?

With the car running plug the Garmin into the cigarette lighter outlet. Does it come on without pushing the ON button? If the answer is no then there is either a problem with the cable or the cigarette lighter outlet. It should come on by itself if the lighter is working. Also are you using Garmin cables and DC adapter?
