That spring is very important. If you remove the metal tip at the end of the charger, there is a spring on top of a fuse. The spring keeps the metal in contact with your vehicle's charger. Without that, it will not charge. Your only options are to purchase a new cord from Garmin, or charge the unit thorough the computer.

My Garmin Nuvi 52LM will not turn on when I start the car with the cord in place.

1. Make sure that the charger outlet is supplying +12VDC. Try another device by plugging it into the outlet and seeing if it powers on.

2. Make sure that the fuse in the charger tip is not blown. The tip usually unscrews. It is spring loaded so be careful that the fuse, spring and power tip are not lost. Check the fuse. It should read 0 ohms with an ohmmeter. If it is glass hold it up to the light and see if the wire inside is open (broken). If the fuse is bad, replace it with the same value.

3. Make sure that the charger outlet is controlled by your ignition. If the the unit is on all of the time, regardless of the ignition setting, then the outlet is wired directly to the battery via a fuse.

4. Does the unit power up on its internal battery? Is the charger working? If it is bad, the unit will not power up when plugged into a 12VDC outlet.

Garmin GTM 25 charger cord has broken wire inside.

Most likely that is the FM antenna lead that goes to the traffic receiver. It should only be connected on the end that goes to the receiver.

You say the GTM-25 is not charging. Is the fuse blown? The charger takes +12VDC from the lighter socket and supplies +5VDC to the GPS.

My tom tom keeps switching off as tho out of power even tho plugged in. the charger gets extremely hot as does the wire, any suggestions? it is about 3 years old

You need to plug your TOM TOM into a PC with Internet connection and go to the tomtom web site:
You will need a usb cable that has the "mini" usb standard connector that plugs into the TOM TOM unit. It should update automatically, but you will need a TomTom Home account (free) created. Then you can download the latest updates that should clear up the power issues. Otherwise, get a new power cord as they do wear out with daily use. -Greg

My Garmin MAP 295 won't power up. Third time in 5 years.

I have discovered an intermittent problem on my 10 year old 295 when powered by batteries.
It appears that the chrome plating is de-laminating from the battery contacts that are either side of the back panel attachment hole. At first glance it looks perfect but if you run a fingernail or other small item across the face of the contact you will see and hear a movement as if there a a loose layer of foil over it. This is causing all manner of faults including 'external power lost, shut-down in 30 seconds' when the external power was not even connected at all!

The end of my 12 volt power supply cord was lost.

You might be able to use the parts from an old cell phone adaptor. Have you tried that?
If not don't mess with any off brand adaptor. Get another one from Garmin at their website Garmin .com

Power supply

Three years ago I performed a temporary repair to the power cord on my motorcycle. Someone unfamiliar with the connection pulled the cord instead of sliding it. The hard plastic flange pulled away from the molded rubber plug. I glued the lower flange back to the plug with superglue. It's still working.

Power cord contact loose

You can use tinfoil on the inside of the female connector. this will basically allow it to be conductive. The best solution is to go radio shack and get another plug and soder it in place but this can be a little tricky. So see if the tin foil will work for you.

Power pin fell off inside of Magellan Roadmate 3000T

I managed to solder my connector back in place. The ground trace broke away from the board so I had to install a jumper to ground. I put RTV on the connector to secure it after the repair.
Worked great for a few weeks until it was dropped again and lost power, something else has a broken connection.

Won't turn on

One of the wires in your power cord could be broken. If you have the a/c adapter, see if you can power up with that. If you know someone else with a working Magellan, you could borrow his cord to test your unit.

If not, check the car adapter with a continuity tester. Put one tester probe on one of the side springs of the car plug and the other probe on the outside metal of the GPS plug. If that shows continuity, place one tester probe on the end tip of the car plug and the other inside the the GPS plug.

If either of those do not show continuity, first take apart the auto side of the cord. Check the fuse and the wire to contact solder joints. If they seem okay, carefully cut back the molded plastic from the GPS end and examine the wire to solder joints. If any are broken, replace the cord or resolder the joints.

Magellan Roadmate 800 - External Power Connection

The only thing I can think to add is a general question to Magellan asking why they let a four-year-old child design the power connector as "lightly" soldered to the main circuit board. Very dumb...
