How do I know my
zūmo is in USB Mass
Storage Mode?
When your zūmo is in USB Mass Storage Mode, a picture of a
zūmo 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 zūmo is
connected.
1. Unplug the USB cable from your computer.
2. Turn the zūmo off.
3. Plug the USB cable into your computer and your zūmo.
The zūmo automatically turns on and goes into USB Mass
Storage Mode.
I cannot find any drives
named “Garmin” in my
list of drives.
If you have several network drives mapped on your computer,
Windows may have trouble assigning drive letters to your
Garmin or SD drives. Follow the steps on the next page
to
assign (map) your drive letters.
I get a message saying
“Unsafe Removal of
Device” when I unplug
the USB cable.
Windows: Double-click the
Unplug or Eject
icon in your
system tray. Select
USB Mass Storage Device
and click
Stop
.
Select the Garmin drive and click
OK
. You can unplug your
zūmo now.
Mac: Drag the volume icon to the
Trash
. The Trash icon
changes to an
Eject
icon. You can unplug your zūmo now.
