Hi, You can get the power adapter pin replaced at an Electronic store. Radio Shack has it but it must be special ordered, have you tested the power cord? I think that you might be right about the power socket cause thats what most common problem of the ones that I repair.

Won,t turn when plugged into car.cigarete lighter has power,fuse is good in garmin unit


Check the cable that plugs into the unit itself. It possibly is damaged and will not acknowledge the GPS. Try replacing the car charger/ac adapter. Check NewPower99.com. they have a lot of inventory and great pricing. Good Lucl!

Car adapter not working, i can power unit from usb. fuse is good on car adapter and 12 volt outlet is working. can i test tthe power out of the adapter?


The only way to test the car charger for the 765T is with another satnav. However the problem is most likely that the fuse in the plug of the car charger is blown. Near the top of the plug, that goes in the cigarette lighter socket, there's a ring. On most plugs it's silver but it's black on some. Unscrew the ring and the plug comes apart. Be careful not to lose the silver nipple at the end of the plug. When you take it apart you will see the fuse. Replace the fuse and the problem should be solved.

Port for car charger broken


the following advice pertains to the following magellan gps systems.

Magellan 800, 860, 2000, 2200t, 2500, 3000, 3050, 3100, 3140, 4000, 4040, 4050 and 6000t

i fix these and many other magellan gps daily so when considering my advice , please understand i do not google my solutions.

assuming your car charger is working (the little green light is on) and your magellan still wont start up after holding the power button while its plugged in for up to ten seconds and still does not start..read below

this is actually a very common problem with these magellan power ports...they are poor quality from the factory and always and i mean always fail..the new ports that you find on ebay are 100% better then the factory port.

if your able to replace that power port yourself, you can get one HERE, if not, ask the fellow that sells them for help.

due to some dubious "experts" on fixya, im not permitted to help you directly, but please follow the link above to get further help.

let me know if you need more help or info

GPS doesnt turn on with power cord adaptor or 12v lighter socket


if you can verify that the car charger is ok, try plugging it in to your computer using the usb cable. the 1412 should charge with the usb cable. if it still doesnt turn on, try and reset the unit,little pin hole on the side.

Plug in car charger and it shows navigon connected to computer


The problem lies with the fact that a standard mini usb pin-out has + voltage on pin 1 and ground on pin 5. The navigon is programmed to recognize this as a computer. The navigon charger however has + voltage on pin 4 and ground on pin 5. The reason for navigon doing this as opposed to following the standard pin-out is due to the unit requiring a stronger power supply to charge the battery. USB current output on a computer does not have the capacity to do this. As a consequence, you will have to find a charger that has the right pin-out for this device ( + on pin 4 and - on pin 5 ). The tough thing is, there is no way to tell one from the other, they look identical. However, I have found that chargers with a capacity of 1000 ma or greater are pinned-out like above ( + on pin 4 and - on pin 5 ). Other than using a multimeter to verify the pins, the only thing to do, would be to plug it in and see if it works. Hope this helps.

Nuvi 350 wont charge with car adaptor. But charges with ac charger in usb port of Nuvi. Any thoughts? I have another Nuvi 350 that does charge with this ones car adaptor.


Are you using the same port on the Nuvi to connect the car adapter and the ac charger, or two different ones? If not, then the jack could be broken (solder joint, pin?).

WE CHARGE THE MAGELLAN GPS AND TURN IT OFF. BUT WHEN WE GO TO USE IT AGAIN IT IS DEAD. I ONLY HAVE THE LIGHTER OUTLET TO HOOK UP FOR POWER SO WHEN I NEED TO PROGRAM IT IN THE HOUSE I DO NOT HAVE A WAY TO...


Hello kdiltzbook,

Most GPS units can be charged three different ways:

1. Connection to a computer via USB port
2. Connection to a automobile via cigarette lighter plug
3. Connection to a wall outlet via an AC adapter

Typically most GPS devices these days include only the USB cord. Some GPS units also include the cigarette lighter plug. For most GPS units the cigarette lighter plug and AC adapter are optional accessories have to be purchased in addition to the GPS.

You don't mention which model of Magellan GPS you have so I am not sure which cords your GPS should have included. It sounds like you have the cigarette lighter cord and the USB cord? I am sure that Magellan has an AC adapter available for your GPS. You will want to contact them directly (their website is http://www.magellangps.com) or visit an electronics store that sells Magellan GPS receivers (such as Best Buy™) to purchase the adapter.

However, most GPS receivers can be charged from the USB programming cord on the computer. However, ensure you are plugging the cord directly into a USB 2.0 on the computer itself NOT a port on a USB hub. (A USB hub may not output enough power to actually power and charge the GPS.)

You will also want to check and replace the fuse on the automobile plug.

I believe that both the USB and automobile cords should be charging the GPS. If neither adapter is charging the unit then the problem may be the GPS unit itself. The GPS may have a bad battery or problem with its charge circuitry. If that’s the case the unit may require factory service as the battery pack is generally not considered to be end user replaceable.

Nuvi 650


Hello Grumpa1350,

There are several possible reasons why a GPS unit might not turn on. For example, there could be something wrong with the charger such as a blown fuse, bad power adapter, or defective cable connection. The internal battery inside of the GPS also might be defective or worn-out. Or, worse yet, the unit may have a more serious hardware fault.

You don't say how you are charging the unit. I'd recommend trying a different charge method. The GPS can be charged one of three ways: connection to you car via the automobile power cord, connection to your computer via a USB cable, or charging from a wall outlet using an optional AC adapter. If you are charging the unit in your car, try connecting it to your computer (or vice versa). If the GPS turns on after being charged using one method but not the other, then that pretty much tells you that the problem is with the cable or adapter being used for charging.

The Garmin NUVI 650 does not contain an internal fuse, but there is a common 3 amp fast-blow fuse located in the vehicle power cord. If you find that the problem happens when trying to charge the unit in your vehicle, then you should change this fuse and see if that corrects the issue. The fuse can be replaced by unscrewing the black round piece at the end of the cigarette lighter plug.

If the unit does not turn on regardless of what charge method you use, then the fault is likely with the GPS itself. Either the internal battery would need to be replaced or the unit would need to be serviced to correct whatever hardware fault is causing the problem.

I would recommend you contact the manufacturer before you attempt to open up the unit. Opening the case of the GPS may void your manufacturer's warranty (if the unit is still under warranty).

Best regards,
Ken

No power


Two possible solutions. One is that you buy a cradle in which you put the gps unit on it or just buy a new one. Usually if the pin is broken, it needs repair.

Magellan GPS does not turn on


I've got one that has a problem with the power connector. Look on the adapter thingy (has the female power socket along with the usb socket). With a pin, wiggle the center power pin. If it is loose, this is the problem. Carefully use a knife to open the adapter thingy (it's glued together). Go to Radio Shack/Fry's and get a replacement power female socket that solders to the little PC board in the adapter thingy. This will fix it. Allen
