How to power Garmin with USB?

I installed usb power port on my 2011 Wee. When I plug in the usb for power all it shows is a PC connection. Is there a special usb cord for power supply? I read this article Can You Power Your Garmin With a USB Cord? | Tech Tips - Salon.com and it says I need a special cord for power supply. Can anyone help with this?

If you cut the data pins, all you have left is 5 volts and ground. Do a google on USB pinouts.

That should work. Power pins are the two outside ones, or if you're looking at the wires, the red and the black ones. You can also buy a power cable with the data lines already disabled (or not connected).

In the Garmins I've had sometimes if you leave the data cable plugged in and powered, after few minutes the GPS functions start up on their own.

Many device is looking from data lines if it is connected to charger or as data connection to computer. If data lines are shorted, device thinks that it is connected to charger.
Here is link to instructions how to hack USB cable to be used as charger.
Charge Only MicroUSB Cable | Sean O'Steen Charge Only MicroUSB Cable | tinkerer
( I have not tried this, but USB charging spec state same thing)

Previous info works with many other devices, but Garmin seems to have different way.



Garmin charging cable should have 18K ohm resistor between pin x and pin 4.
Mini USB connector is so small that it is not easy to hack it open and solder resistor between pins.

Best option is to buy ready made cable, but you need to check that cable is made for charging Garmin GPS.

I google more about garmin ubs power and found this trick:
"Found that when connecting USB power the nuvi enters to PC mode, I unplug the mini USB cable, and when the computer symbol dissapears ( nuvi wants to restart ) Then immediatly plug the USB mini cable back in. Nuvi will then works as a GPS, and gets charged at the same time."

I tested with my old nuvi and it works. You need to spend 30 seconds for doing it, but then you can run Nuvi in GPS mode with external power using standard cable.

UPDATE

I decided that the USB would not fit my needs so I sold it to another member. I went with a Blue Sea Socket. 12 Volt Dash Socket - Blue Sea Systems
Everything fit and works well.

Looks good. I am going with something similar, a Blue Sea dual USB. I am just waiting for my wiring pig tail that plugs into the factory supplied 12v plug that I believe is for heated gear.

I was going to go the USB socket mount (in fact I already bought it) but then decided to try this:

All I need to do is figure out where to hide the mid-cable box.
