Sorry to hear of the dead units. Are you using the correct power cable with a small hole in the centre of the plug? The GPS 12 is strictly limited to 7 volts only. The accessory cigarette lighter cable for this model has a circuit inside to drop the voltage from 12 to 7. Cannot be fixed. There would have been a plastic peg in the back of the GPS socket to prevent anything but the correct voltage Garmin cable being plugged in. Unfortunately these pegs are easily broken off. Yes, they are a good little unit even though well on in years. The next model up - the 12XL - can accept a wide voltage range and does not have the plastic peg.

All the best, Tony at KiwiGPS.

Have a six month old StreetPilot 7200 and the 12 volt cable stopped working. Unit apparently gets no power. Works fine with 120 V AC cable. Garmin says they have no parts for this unit. Is there a simple...


First, make sure that the unit really does run off of +12V. Most Garmin units really run off of +5VDC and there is a charger/regulator that reduces the +12VDC to +5VDC. Look at the power cable and see what the output voltage is. Does the unit has a USB port?

Charged garmin forerunner 110 with 12 volts for split seconds and won't turn on anymore?


Power supply damage is most likely and depending on cost of the unit itself may or may not be worth fixing---kind of like hooking a radio up backwards on a 12 volt system--damage is INSTANT and sometimes fatal.

I have a 8 year old garmin GPS model 12 that may be dead. When I turn the red power button on the garmin sez "upload not present". Also the rubber at the base near the batteries has rotted. Thanks for any...


I had the same problem and it took me some time to make my cable. I got this info from fix ya. Reload the software for your unit, I googled garmingps12 and went to downloads from the garmin selections.The software is not compatable with vista, so I ended up using my old computer to do the job. http://pfranc.com/projects/g45contr/assemb.htm
This web site gives good information on making your own cable.
I hope all works for you as it did for me. justaxiom

12volt usb in the side of my Garmin now dead


unfotunately only an electronics expert can fix this if it is indeed salvageable. You basically have cooked the circuits with the power over load.

Garmin nuvi 5000 wont turn on. I can plug up the usb up to the computer and the screen shows garmin logo with a gps connected to a computer like its charging. But when i press the power button weather it...


Your nuvi 5000 does NOT have a internal battery and that means that you cannot operate it unless it is connected to a 12 volt power source. Connecting it to your computer via USB allows you to install map updates, check for firmware updates, etc, but you will not be able to use it as a gps while it is connected to the computer. There is nothing wrong with your gps.
To use your gps in the home you need to purchase a 12 volt adapter, there are several types, plug the adapter into your wall outlet and connect your gps to it. If you can sit near a window it will help in picking up the satellite signal. Just keep in mind that you cannot connect the 12 volt power supply and use the usb cable at the same time. Enjoy your gps.

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

Question: Why won't my unit charge while plugged into my vehicle?
From the Garmin site: --> Answer: 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.
  1. Unscrew and remove the silver or black, round end piece. fileservlet?date=1&kb={6b85cfa0-194d-11dc-44cd-000000000000}&id={6e53bea0-6874-11dd-436f-000000000000}&ext=jpg
  2. Remove the fuse (glass and sliver cylinder) and replace with a new fuse.
  3. Ensure that the silver tip is placed in the end piece. Screw on the end piece.

I had the same problem recently... What I did was open the front casing and hit the reset button under the cover, then it turned on while plugged into the car adapter.
