have you tryed your sony help line?

your map data was stored in the lost sd card and replacing that you wont find the data again so reinstall the map software

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:

1. Connect the device to the computer using the USB cable
2. Go to the Main Menu
3. Select Setup
4. Select Interface
5. 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:

1. Select the Tools option on the window that appears on the computer when the device is in USB Mass Storage Mode
2. Select Folder Options
3. Select View
4. Open the Files and Folders folder
5. Open the Hidden Files and Folders folder
6. Select Show hidden files and folder
7. Select Apply
8. Select OK

Once all of the hidden files and folders have been removed from the microSD Card the unit will not

Shane080,
how do you unlock c520?
please advice...

card is possibly blank send it back. buy a marbella altina Nextar are unreliable GPS If in Australia see www,nettiser.com.au/marbella/
e3ven outside australia the maps are available for all countries and the unit is reliable and easy to service, also has a mkap backup service if registered.

I called Nextar and you have to let its battery drain completely and then plug it in to charge for 5 hours. I guess it a glitch in the system :(

I HAVE A SIMILAR PROBLEM WITH MY W3G-01. THE ERROR MESSAGE READS; CANNOT FIND MAP DATAFILES. PLEASE MAKE SURE THE STORAGE CARD IS PROPERLY INSERTED. I HAVE REMOVED CARD AND REINSURTED IT AND THE MESSAGE REAPPEARS.

Ok So I now have these 2 files on my pc, virus free. One is the Map_SD and one is the Install_SD. I unzipped them to folders of the same name.

Can I simply copy and paste both folders into a 1gb sd card and it will work ( I have to buy an sd card so Id like to make sure)

Thanks

you need to reload the firmware in the unit and reload the map data on the SD card, this will fix your issues. as finedrive is not around anymore, here are the files:
