How do I know my nüvi 

is in USB Mass Storage 

Mode?

When your nüvi is in USB Mass Storage Mode, a picture of a nüvi 

connected to a computer is shown. Also, you should see a new 

removable disk drive listed in My Computer (Windows) or a new 

volume (drive) on your desktop (Mac). 

My computer never 

senses that the nüvi is 

connected.

1. Unplug the USB cable from your computer. 
2. Turn the nüvi off and then back on again. 
3. Plug the USB cable into your computer. The nüvi automatically 

turns on and goes into USB Mass Storage Mode. 

I cannot find any drives 

named “nuvi” in my list 

of drives.

Try the solution listed above. 
If you have several network drives mapped on your computer, 

Windows may have trouble assigning drive letters to your nüvi drives. 

Follow the steps on the 

following page 

to assign your drive letters. 

Verify that your computer has the latest updates installed. If not, 

update your computer, and then connect the nüvi. 

I keep getting a message 

saying “Unsafe Removal 

of Device” when I unplug 

the USB cable.

Windows users, double-click the 

 

 icon in your 

system tray. Select “USB Mass Storage Device” and click 

. Select 

the nüvi drives and click 

. You can unplug your nüvi from your 

computer now. 
Mac users, drag the volume icon to the 

. The Trash icon 

changes to an 

icon.
