f a device is locking up and has a long noise or beep when powering
down, this is due to hidden data being transferred to the microSD data
card. These hidden files and folders are being created by the computer
and sent to the data card in addition to the maps, waypoints, routes,
tracks and pictures that were selected. The following GPS units could
experience this issue.
- eTrex Legend Cx
- eTrex Legend HCx
- eTrex Venture Cx
- eTrex Vista Cx
- eTrex Vista HCx
- GPSMAP 60Cx
- GPSMAP 60CSx
- GPSMAP 76Cx
- GPSMAP 76CSx
- Rino 520HCx
- Rino 530HCx
To
prevent this issue when the device is shutting down delete these extra
unused or hidden files and folders from the data card. Examples of these
folders are: .Trashes and .Spotlight-V100 folders. Since the Mac OS
adds hidden files and folders to mounted removable drive volumes this
process cannot be done on a Mac and will need to be done after every
time the data card is mounted as a volume on a Mac.
To delete these folders the device will have to be placed into USB Mass Storage mode. To do this:
- Connect the device to the computer using the USB cable
- Go to the Main Menu
- Select Setup
- Select Interface
- Select USB Mass Storage Mode
The
device is now in USB Mass Storage Mode. At this time a window should
open on the computer desktop displaying Removable Disk at the top. The
Garmin folder will be displayed. Open the Garmin folder.
Do NOT delete the the following files:
- gmapsupp.img
- gmapsupp.unl
- gmapsupp.gma
These files contain supplemental mapping. If delete will cause the mapping to be erased or unviewable.
If
there are other folders or files on the data card, delete these. Some
of these files or folders may be hidden and therefore will need to be
unhidden*. Once you have done so, please disconnect the device from the
computer and power it up.
*Note: To Display a file folder that is hidden:
- Select the Tools option on the window that appears on the computer when the device is in USB Mass Storage Mode
- Select Folder Options
- Select View
- Open the Files and Folders folder
- Open the Hidden Files and Folders folder
- Select Show hidden files and folder
- Select Apply
- Select OK
Once all of the hidden files and folders have been removed from the microSD Card the unit will not
