(You can use your nuvi while charging.)
After this mod your cable cannot be used for usb access ever again so make sure it's a spare cable.

Tut:
Take a spare nuvi usb cable.
Somewhere in the middle of the cable carefully cut open the insulation using a sharp Stanley knife or razor blade (Be Careful not to cut open your fingers.)
Cut the 2 data lines (2 colored wires, usually white and green ) Do not cut the RED or Black wires.(Power)
Now Insulate the cut wires on both sides using some shrink tube.
Tape up the cable neatly.

On Nuvi 1xxx the Nuvi will boot into Mass Storage mode for a short while and then boot again to where to screen.
On 3490 the Nuvi will work normally.

Not work with Nuvi 2595! I have cable like this. I made it for my Dakota 20 and work without a problem with. I hope it's work with my new Nuvi 2595 but I was disappointed.
